Question

Question 2 (1 point)
When a light wave enters a medium of greater density, which of the characteristics below will decrease in the wave.

a
Frequency
b
Amplitude
c
Height
d
Speed
Question 3 (1 point)
1a862de7-5222-4ed5-bcba-8b8c836d45d7

The wavelength of the wave in the above diagram is:

a
2 m
b
Cannot be determined from graph.
c
3 m
d
6 m

Answer 1

Question 2: d — Speed.
- When light enters a denser medium its speed (and wavelength) decrease; frequency stays the same.

Question 3: b — Cannot be determined from graph.
- Without the actual diagram or an x‑axis scale showing distance between successive crests/troughs, the wavelength cannot be determined.
