B)speed of transmission of the waves is increased.
C)wavelength and speed of transmission both increase.
D)wavelength remains constant.

Question

Quizplus · Accepted Answer

The wavelength of a wave is inversely proportional to its frequency, according to the wave equation. Therefore, when the frequency is increased, the wavelength must decrease. The speed of transmission of the wave is constant and is not affected by the frequency or wavelength.
