One diopter is the power of the lens with the second focal length

Answer»

'' The POWER in DIOPTERS ism the reciprocal of the focal length in meters(or meters,if you prefer). So a focal length of 1 m is 1 DIOPTER, while a focal length of 0.25 m is 4 diopters. If ''2.5 power'' REALLY means 2.5 diopters,then the LENS' focal length is 400 m.

Can you tell me difference between evaporation and vaporization

Answer»

Evaporation is the process of a substance in a liquid state changing to a gaseous state due to an INCREASE in temperature and/or pressure.
Evaporation can happen at any time since the liquid MOLECULES absorb energy from the surroundings and change to gaseous form, cooling the area from where it evaporated.

Vaporization is the process phase change from liquid to gas state but above the BOILING point of the liquid. Vaporization can only happen if the liquid is BOILED above its boiling point.

What is the dew point when it is raining?

Answer»

At a tropical 86 degree,it it can hold twice as much as it COULD hold at 68 degree. That,to PUT it simply,is why it rains. The DEW point is the temperature at which the air can exactly hold the amount of moisture present. If the temperature falls below this value,some of the water vapour MUST condense.

Two forces of 5N and 7N act on a particle with an angle of 60 degree between them. Find the resultant force.

Answer» RESULTANT of any two vectors is given by FORMULA
R = √(V1*v1 +V2*V2 + 2v1v2cos(angle between them))
so, resultant is √( 25+ 49 + 70*1/2)
=√(74 +35)
=√109

Write a note on yellow spot and blind spot

Answer»

Yellow Spot

This section is about the 
Anatomy of the Human Eye



The yellow spot is a small depression forming a shallow pit in the retina at the back of each eye in the human body. It is slightly yellow in APPERANCE and so was first called the 'yellow spot' or 'macula lutea' of Sömmerring, who was the scientist who first discovered and documented it.

As is true of MANY words used in anatomy, the word yellow spot has many SYNONYMS, in this case 'macula lutea' and fovea. Different words are used in different TEXTBOOKS but the meaning is the same.

Due to the large number of the light-sensitive photo-detector cells called cones LOCATED in the region of the yellow spot, this is the area of greatest acuity of vision. Hence when an eye is looking at an object, the part of the image of that object formed on the retina of that eye that is located on the fovea is the part of the image that will be perceived in the greatest detail.

The existance of such an area is only known to occur in humans, the quadrumana (a group of primates comprising apes and monkeys), and some saurian reptiles.
