B.
frequency and speed
C.
wavelength and speed
AnswerD.
frequency, wavelength and speed
Answer: Option C
Solution
Answer: Option C
Solution:
When light passes from air into glass it experiences change of wavelength and speed. Waves change speed when they pass across the boundary between two different substances, such as light waves refracting when they pass from air to glass. This causes them to change direction and this effect is called refraction.
