--Suppose a ray of light travels from air into water.

a. If the air has an index of refraction of n = 1.0, and the light enters the water with an angle of 55 degrees to the normal, and the refracted angle is 38 degrees from the normal, what is the index of refraction of the water?

b. Can total internal reflection occur when the light ray passes from the air to the water? Why or why not?

--Which of the following statements are correct?

a.For both concave and convex mirrors the virtual image is always behind the mirror.

c.The virtual image formed by a convex mirror is inverted, enlarge.

d.For both converging and diverging lenses the virtual image is always on the same side of the object.

e. The virtual image formed by a converging lens is erect, reduced.

f.The virtual image formed by a diverging lens is inverted, enlarged.

Expert Solution

Option A is correct as For both concave and convex mirrors the virtual image is always behind the mirror.

Option B is incorrect as the The virtual image formed by a concave mirror is erect, but enlarged not reduced.

Option C is Also incorrect as the virtual image formed by a convex mirror is erected and diminished.

Option d is Correct as for both converging and diverging lenses the virtual image is always on the same side of the object.

Option e is Incorrect as the virtual image formed by a converging lens is magnified and upright.

Option f isIncorrect as The virtual image formed by a diverging lens is reduced and erected.
