is Doppler effect in the syllabus of class12th 2020 boards cbse​

Answer 1

Answer:what

Explanation:

Answer 2

Given that,

Doppler effect

We know that,

Doppler effect :

The frequency of the sound increases when the source moves near to the observer it is called doppler effect.

In other words,

The doppler effect is equal to the addition of velocity of sound wave and observer velocity divided by subtraction of sound velocity and source velocity and multiplication by source frequency.

In mathematically.

$f '=\dfrac{v+v_{o}}{v-v_{s}}\times f$

Where, v = velocity of sound wave

f = source frequency

f'= observer frequency

$v_{o}$ = observer velocity

$v_{s}$ = source velocity

Hence, The doppler effect is the change of frequency of source,
