Answer the following questions about mirrors and lenses.
(a) A .45cm object is placed 30.0cm in front of a concave mirror
with radius of curvature of 40.0cm. i. Find the image distance, di
. ii. Find the magnification of the image, m and the height of the
image, hi . iii. Is the image real or virtual? Upright or inverted?
iv. Draw a ray diagram.
(b) The same object is now placed 30.0cm in front of a biconcave
lens (n = 1.62) with both of its sides having a radius of curvature
of 40.0cm. i. Find the image distance, di . ii. Find the
magnification of the image, m and the height of the image, hi .
iii. Is the image real or virtual? Upright or inverted? iv. Draw a
ray diagram.
(c) What happens when an object is placed at the focal point of
a concave mirror, a converging lens, and a diverging lens
respectively? (In other words, where is the image, and what is the
magnification of the image?) What if the object is placed at
infinity?
