When frequency is increased propagation speed also increases?

Answer 1

Nothing. Frequency doesn't control the speed of a wave.

Increase in frequency will reduce the wavelength of the wave to keep the velocity constant (v=nu x lambda)

Answer 2

If youre talking about sound waves the speed of propagation stays the same regardless of frequency or amplitude.

For most types of waves, propagation speed depends almost entirely on the medium through which the wave is being propagated. Most of the time when studying waves, the propagation speed is a constant and only f (Frequency) and λ (wavelength) vary. For sound, the propagation speed depends on a number of things, primarily the composition and density of what the sound waves are propagating through. For instance, sound propagates more quickly through the more dense air near sea level than it does in the less dense air at, say, 40,000 ft. For electromagnetic waves (radio, microwaves, light, x-rays, gamma rays, etc.,) the propagation speed is the speed of light. In a vacuum, this is c, which is exactly 299,792,458 m/s. This number is exact because the SI unit for a meter is defined in terms of c (a meter is defined as the distance light travels in vacuum in 1 / 299,792,458 seconds.) In non-vacuum, like the speed of sound, the speed of light varies based on the composition and density of the material through which the wave is propagating. However, it should be noted that sound does not propagate at all in vacuum and its propagation speed increases with higher density media, whereas light propagates fastest in vacuum and more slowly through more dense media.

Answer 3

as the frequency increases, the wavelength gets shorter.

Answer 4

Wavelength of the wave decreases.
