Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
What happens to wavelength as the frequency of a wave increases?
A
increase
B
stays the same
C
decreases
D
becomes faster
Explanation: 

Detailed explanation-1: -From these equations you may realize that as the frequency increases, the wavelength gets shorter. As the frequency decreases, the wavelength gets longer.

Detailed explanation-2: -As the wavelength decreases and frequency increases, the energy increases-for example X-rays and gamma radiation.

Detailed explanation-3: -Wavelength is decreased in a medium with slower propagation. Refraction: upon entering a medium where its speed is lower, the wave changes direction.

Detailed explanation-4: -Wave speed equals frequency*wavelength. So doubling the frequency must halve the wavelength in order for wave speed to remain the same.
