Yes, as density is a value which is the same for any substance and does not change due to different volumes or masses of the same substance
The Doppler effect says that the observed wavelength is shortened
when the source is approaching the observer, and lengthened when
the source is receding from the observer.
All we can say about the police car and its siren is that the sound/color
has a shorter wavelength as it approaches us, and a longer wavelength
as it recedes.
Any of these pairs of answers would say that:
A -- A
C -- A
D -- A
or
D -- D
For each of these pairs, the second wavelength is longer than the first one.
(We don't know which pair is the actual one, because we don't know the actual color of the police car.)
From the data in the given table, it can. be concluded that the angle of refraction decreases with increasing wavelength.
<h3>What is wavelength of light wave?</h3>
The wavelength of a wave is the distance between two successive points on the wave.
The wavelength of a wave is usually measured in metres.
The angle of refraction is the angle to which a wave is bent from the normal.
The color of light that has the shortest wavelength is Red while violet has the longest wavelength.
From the table provided, it can be seen that the angle of refraction decreases with increasing wavelength.

Hot air is less dense than cold air, causing it to displace and rise to the top.
