Question

An object is placed at a distance of 25 cm from the concave mirror of a focal length of 10 cm. Calculate the image distance, draw the ray diagram and also find its magnification. please answer as soon as possible.

Answer 1

u = -25 cm

f = -10 cm

1/v + 1/u = 1/f

1/v - 1/25 = -1/10

1/v = 1/10 - 1/25

1/v = 5-2/50

1/v = 3/50

therefore, v = 50/3 OR 16.66 cm

m = -v/u

m = (50/3)/-25

m = 50/3 x 1/-25 = -2/3

am sorry, I cannot send the ray diagram, anyways keep the object beyond C (2F), and the image that you will get will be smaller than the object
