If the frequency of a wave decreases but its wavelength remains the same,what else will decrease in the wave ?

Answer 1

velocity is frequency times the wavelength
so if the frequency decreases the velocity also will decrease

Answer 2

This is obviously not a question about electromagnetic waves.

The frequency is a measure of the number of waves passing a point in a particular time interval. The wavelength is the distance between successive peaks.

If the frequency decreases but the wavelength doesn't change then since fewer peaks have passed the point the velocity of the wave must have reduced. ie the wave slowed down.

Answer 3

It relies upon on how plenty the wavelength and velocity replace. f will continuously be equivalent to v/lambda the place v = velocity and lambda = wavelength. no longer adequate records to tell. in case you bigger v via a component of two, and lambda via a component of three, then v/lambda might decrease. in case you bigger v via a component of three and lambda via a component of two, then v/lambda might improve.
