tion:FRINGE width, β=Dλ/d When the distance D between the SLITS and the SCREEN is doubled, the fringe width also gets doubled.PLEASE make it brainlist ANSWER please

The vertical axis represents the acceleration of the object. For example, if you read the value of the graph shown below at a particular time, you will get the acceleration of the object in meters per second squared for that moment. Try sliding the dot horizontally on the graph below to CHOOSE different times, and see how the acceleration—abbreviated Acc—changes.    Concept check: ACCORDING to the graph above, what is the acceleration at time t=4\text{ s}t=4 st, equals, 4, start text, space, s, end text? [Show me the answer.] t=4\text{ s}t, equals, 4, start text, space, s, end text+1\dfrac{\text m}{\text s^2}     plus, 1, start fraction, start text, m, end text, DIVIDED by, start text, s, end text, squared, end fractiont=4\text{ s}t, equals, 4, start text, space, s, end text+1\dfrac{\text m}{\text s^2}

tion:A wavefront is a surface OBTAINED by joining all POINTS vibrating in the same phase. A ray is line drawn perpendicular to the wavefront in the direction of propagation of light WAVE. ... When a POINT source is placed at the focus of a convex LENS, the emerging light has plane wavefronts, as shown in Fig.

hy ur answer isExplanation:The earths motion. isn't NOTICEABLE beacause the mass of EARTH is very much more than that of APPLE . By universal LAW of gravitation Gmm/r2 the earths mass produces the greater inertia as then apple so it's true but not noticeable.Thank you Hope it HELPS .=✌✌✌✌✌✌✌✌✌ Mark as brainiesthope it helps u!!plz mark me as brainliest

1In Young's double slit EXPERIMENT, the spacing between the two consecutive bright and dark FRINGES is given by the IMAGE attached. The dark and bright fringes are equally spaced. Therefore, the ratio of fringe with for bright and dark fringes is 1 KEEP SMILING.......

Frequency is the CHARACTERISTIC of the SOURCE. That is why it remains the same. But WAVELENGTH is charactristic of the medium. So wavelength and veloctiy both CHANGE.

In the wave picture of light , intensity of light is determined by SQUARE of the AMPLITUDE of wave. what determine the intensity of light in the photon picture of light ? The photon density, that is the no. of photons per unit volume at a given POINT DETERMINES the intensity of light in the photon picture of lightKEEP SMILING........

when light travels from rarer to denser medium the SPEED decreases does this imply a decrease in ENERGY carried by the light wave. JUSTIFY. 'h' is Planck's constant and 'ν' is the frequency. When there is a change in medium the frequency of light remains constant and the wavelength of light changes.it depends UPON its amplitude...KEEP SMILING.......

the heightExplanation:because HEIGHT SQUARE + RADIUS square /2

The law STATES that:The magnitude of the ELECTROSTATIC force of attraction or repulsion between two point charges is directly proportional to the product of the magnitudes of charges and inversely proportional to the square of the distance between them.Hope I HELPED!!  : )If i did, could you mark me as brainliest? I would appreciate it a lot! : )EXPLANATION:

(1) SPHERICAL(2)PLANE

When the PATH difference is ONE FULL wavelength, a crest MEETS a crest and constructive INTERFERENCE occurs.

the size decreasesExplanation:As the size of the HOLE is increased, the width of the central MAXIMUM of the DIFFRACTION pattern of hole decreases. Since the same amount of LIGHT is now distributed over a SMALL area, as intensity ∞ 1/area, the area is decreasing so area intensity increases

a. The wavefront is spherical. EXPLANATION:HOPE the ANSWER will HELP you ☺❤

quantities are quantities that are calculated from two or more measurements. Derived quantities cannot be measured directly. They can only be computed. MANY derived quantities are calculated in physical science. Three EXAMPLES are area, volume, and density.For EXAMPLE, area,volume,force,pressure,density etc are few derived quantities.Hope it helps you MAKE it Brainliest

the dielectric CONSTANT begins to drop at a certain frequency. The dipole MOLECULES cannot orient themselves in the LOWER temperature region. HOWEVER, owing to thermal expansion, the ration of the NUMBER of molecules to effective length of dielectric decreases when the temperature increases.

= ..............m ANSWER i DONT now so you ASKED from any ATHER

s the series arrangement not used for domestic circuit?Series arrangements is not used for domestic circuits because:-In a series connection, if one electrical APPLIANCE stops working due to some DEFECT, then all other APPLIANCES would stop working.In a series connection, all electrical appliances have only one switch due to which they can not be turned on and off separately.In a series connection, all the appliances do not get the same voltage as the voltage gets divided in series combination.In a series connection, the equivalent resistance increases too MUCH due to which the AMOUNT of current flowing becomes very small.

The uses of hard WATER are: -Hard water CONTAINS EXTRA minerals but is safe for drinking, cooking and cleaning. -Hard water contains extra minerals. -Water that is "hard" has a surplus of minerals including calcium and magnesium. This does not pose safety or health threats from ingestion or other basic water uses.And the uses of soft water are:-Better Plumbing.-Extra Savings. Not only does soft water save your pipes, but it also preserves your cleaning supply!-Longer Lasting APPLIANCES. Water services your appliances just like it CIRCULATES through your pipes. ...-Healthier Skin.Hoped this helped!! : )

Be a fine SHARP slit WHITE in color at the CENTRE

I'M NOT SURETan ib=refractive INDEX       refractive index=3/2.2=1.3        TAN ib=1.3               ib=(Tan)^-1(1.3) EXPLANATION:

st maxima for infrared light would be farther from the centre than the first maxima for the green light.Option (c) is correct.Explanation:In physics, minima and maxima are formed in a beam of light when it passes through a slit in an experiment. As the light WAVE passes through a prism or slits it is diffracted into different parts. The highest POINT of the light wave is CALLED maximum and is also known as maxima while the LOWEST point is called minimum and is known as minima.

A laser beam is used for LOCATING distant OBJECTS because it does not spread as it MOVES through the MEDIUM and has a very SMALL angular spread. D.

Explanation:PLZZZ refer to the answer given in the ATTACHED photo.Hope ur answer is CLEARED.

then only RED and BLUE lights are present due to ALTERATION

Should be of the same ORDER as WAVELENGTH. ...
