(a) velocity
(b) frequency
(c) wavelength​

Answer 1

Answer:

B) frequency

Explanation:

Frequency is independent of medium

Answer 2

'When sound waves travel from 'air to water', the frequency remains constant.'

Answer: Option (b)

Explanation:

In physics, we know frequency is the 'number of waves' which is passing a fixed point in unit time; and also, the number of 'cycles or vibrations' undergone during 'one unit of time' by a body in 'periodic motion'.

A body when in periodic motion undergoes one cycle after passing through a series of events or positions and return to its 'original state'. Frequency is independent of medium.
