What is the ratio of the speed of light in zircon (n = 1.923) compared to ethanol (n = 1.361)? v1 is velocity of light in the first medium listed, v2 is the velocity of light in the second medium listed. v1 = 0.708 v2 v1 = 0.903 v2 v1 = 1.41 v2 v1 = 1.11 v2

Calculate the index of refraction for a medium in which the speed of light is 2.012×108 m/s, and identify the most likely substance based on Table.

The speed of light changes when it goes from ethyl alcohol (nea = 1.31) to carbon tetra- chloride (nct = 1.641). What is the ratio vct of the speeds?

The sun is 60° above the horizon. Rays from the sun strike the still surface of a pond and cast a shadow of a stick that is stuck in the sandy bottom of the pond. If the stick is 10 cm tall, how long is the shadow?

As light travels from one medium to another (for example, from air to glass), it refracts, or "bends." If v₁ is the speed of light through one medium, and 2 is the speed of light through another medium, then according to Snell's Law, sin(01) V1 sin(82) V2 == where ₁ is the angle of incidence, and 2 is the angle of refraction. Incident Ray Normal Line Angle of incidence 0₁ Air Surface Angle of refraction 0₂ Refracted Ray V1 The fraction is called the index of refraction. For a beam of light passing from air to water, the index of refraction is V2 1.33. If a ray of light passes through the surface of a water at an angle of incidence of 54°, what is the angle of refraction?

Austin did a measurement for the speed of light in an experiment. He found that the speed of light is 4.0 x 1018 m/s in air. When Nancy Drew saw his result, she immediately informed him that he made a mistake. How did Nancy know? O Light cannot have a speed. O His result would be correct if the experiment was done under water. O His result would be correct, if the light medium was in vacuum, but not in air. O None of the choices is correct. O Speed of light cannot be greater than 3 x 108 m/s.

A light ray propagates in Material 1 with index of refraction n₁ = 1.25, strikes an interface, then passes into Material 2 with index of refraction n₂ = 1.37. The angle of incidence at the interface is 0₁ = 27.3°. Determine the angle of refraction 02. 0₂ € 1 Material 1 Material 2

A ray of light is incident on the surface of a block of diamond at an angle of 43.0° with respect to the normal (a line perpendicular to the surface at the spot where the ray hits the block). A fraction of the light is reflected and the rest refracted. What is the angle (in degrees) between the reflected and refracted rays? in degrees °
