1.

A) An object is placed at a distance of 30 cm from a concave mirror of focal length 15 cm. Write characteristic of the images formed. Also draw its ray diagram (5 marks)​

Answer»

Answer:

Explanation:

FORMULA related to focal length f, object-to-mirror distance u and image-to-mirror distance v is given by

solving the above eqn for v, we get v = 30 CM

 

(1) image is formed at a distance 30 cm from concave mirror

(2) SINCE image distance and object distance are same ( both are at 2F), MAGNIFICATION = 1

     Image and object are same size.

(3) image is real

(4) image is inverted
