Question

When a light wave enters a medium of greater optical density, select two of the characteristics that will decrease in the wave,
A speed
B
frequency
С
wavelength
D
period
E
amplitude
F
height

Answer 1

Answer:

The speed (A) will decrease

V = F λ  (the frequency F remains the same to maintain continuity across the interface)

Therefore (C) the wavelength must decrease      

Note: n = speed of light in air / speed of light in medium

Answer 2

When a light wave enters a medium of greater optical density the two characteristics that are: (A) Speed, and (C) Wavelength will decrease in the wave.

It is given that a light wave enters a medium of greater optical density.

It is required to find the characteristics that will decrease.

What is light?

It is defined as the type of waves such as sound waves or ocean waves but waves carry energy. Light does not need any medium to travel.

We know that:

$\lambda =\frac{v}{f}$

Where Lamda (λ) = Wavelength

                        ($v$) = Speed of wave

                        $(f)$ = Frequency of the wave.

The frequency remains the same to maintain continuity across the interface.

thus Speed of wave and Wavelength will decrease.
