1.	a object is placed at a distance of 15cm from a concave mirror of focal length 6 cm.if the height of the object is 4 cm.find the distance,nature and size of the image
Answer» Explanation: Focal LENGTH (f)=10cm Object distance (u)=15cm. Height of the object=6cm. Using the mirror's formula, 1/f=1/v+1/u 1/-10=1/v+1/-15 1/v=1/-10+1/15 1/v=(-3+2)/30 v=-30cm Since, IMAGE distance is negative, therefore,it is real and inverted. Now, magnitude=-v/u =-(-30)/15 =2 Since, magnitude in greater than 1, therefore image is MAGNIFIED Also,m=H of image/H of object. 2=H of image/6 Height of image =12cm. characteristics of image are Real, inverted and Magnified.

Answer»

Explanation:

Focal LENGTH (f)=10cm

Object distance (u)=15cm.

Height of the object=6cm.

Using the mirror's formula,

1/f=1/v+1/u

1/-10=1/v+1/-15

1/v=1/-10+1/15

1/v=(-3+2)/30

v=-30cm

Since, IMAGE distance is negative, therefore,it is real and inverted.

Now, magnitude=-v/u

=-(-30)/15

Since, magnitude in greater than

1, therefore image is MAGNIFIED

Also,m=H of image/H of object.

2=H of image/6

Height of image =12cm.

characteristics of image are

Real, inverted and Magnified.
