Refraction of a wave

Electricity and Magnetism Level 2

Refraction is the change in the direction of a wave due to a change in its transmission medium. The above diagram shows this phenomenon schematically, where a monochromatic light with wavelength λ \lambda is passing from medium I to medium II . At the boundary surface between the two mediums, some portion of the light is reflected and the rest is refracted with 4 5 ∘ 45^\circ refraction angle. Which of the following statements is NOT correct?

a) The reflection angle θ \theta is 3 0 ∘ . 30^\circ.
b) The frequency of the monochromatic light in medium I is greater than that in medium II .
c) The speed of the monochromatic light in medium I is faster than that in medium II .

a) and c) b) and c) a) only c) only

frequency is independent of medum.

Frequency depends on the source of light...and we'll see through the definition of refractive index that speed in medium 2 is more

Oh, I forgot that the speed of the light will decrease in water or liquid.
