The more it is Red shifted.
Explanation:
(a) The period of a wave is the time required for one complete cycle. In this case, we have the time of five cycles. So:

(b) The frequency of a wave is inversely proportional to its period:

(c) The wavelength is the distance between two successive crests, so:

(d) The speed of a wave is defined as:

A false dalse true true false and thats a;ll i know
If we neglet air resistance for both objects then both will fall parallely(at same time) because time taken by both objects is independent of mass. there is famous experiment i.e"feather coin experiment" . normally we think that heaver objects falls faster but this is wrong concept. it depends on medium in which objects are moving.

Answer:
Meter (m)
Explanation:
The wavelenght of a light wave is a measure of the distance between two successive crests (or two successive troughs) of a light wave.
Since the SI units for the distance is the meter (m), then the SI unit for the wavelength is also the meter (m).
Wavelength is related to the frequency of the light wave by:

where
c is the speed of light
f is the frequency of the light
