Question

A laser beam travels through oil in a horizontal direction. Which of the following objects could you put in the oil in the path of the laser beam in order to tilt the direction of the laser beam upward? Ignore partial reflections at the boundaries between media. μltiple answers are possible.

a) Concave lens

b) Convex lens

c) Diverging lens

d) Prism

Answer 1

A prism, convex lens, and concave lens can be placed in the oil to tilt the direction of the laser beam upward.

Step-by-step explanation:

One object that could be placed in the oil to tilt the direction of the laser beam upward is a prism. When light passes through a prism, it refracts or bends so that the direction changes. By placing a prism in the path of the laser beam, the beam will be tilted upward.

Another object that can be used is a convex lens. Light is refracted toward a focal point as it travels through a convex lens. By placing a convex lens in the oil, the laser beam will be refracted and its direction will be tilted upward.

A concave lens can also be used. When light passes through a concave lens, it is refracted away from a focal point. By placing a concave lens in the oil, the laser beam will be refracted and its direction will be tilted upward.
