Question

State the mirror formula for determining the focal length of spherical mirrors. Write the meanings of the symbols used. An object is placed at a distance of 25 cm. from a concave mirror of a focal length of 15 cm. Calculate the distance, position and nature of the image from the mirror. Draw the corresponding ray diagram.

Answer 1

Answer:

1/ (object image) = 1/(image distance) + 1/ (focal length)

focal length= curvature/2

the equations are:

1/0 + 1/1 = f/1

F= 2/r
