**Step-by-Step Solution:** 1. **Understanding Beats in Sound:** - Beats are a phenomenon that occurs when two sound waves of slightly different frequencies interfere with each other. The result is a variation in sound intensity, perceived as alternating loud and soft sounds. 2. **Definition of Beats:** - Beats can be defined as the result of the superposition of two waves with a small frequency difference. The constructive interference occurs when the waves are in phase, resulting in a louder sound (peak), and destructive interference occurs when they are out of phase, resulting in a softer sound (trough). ...

In sound, beats are heared when two independent sources are sounded together. Is it possible in the case of sources of light ?

Statement I: In YDSE, if separation between the slits is less than wavelength of light, then no interference pattern can be observed. Statement II: For interference pattern to be observed, light sources have to be coherent.

Two light sources are coherent when

A source and an observer are situated on two perpendicular tracks as shown in the figure the observer is at rest and source is moving with a speed 50m//s the source emits sound waves of frequency 90Hz which travel in the medium with velocity 200m//s the frequency of sound heard by observer when the source crosses the origin is

A sound source is moving with speed 50 m//s towards a fixed observer. Frequency observed by observer is 1000Hz . Find out apparent frequency observed by observer when source is moving away from observer (Speed of sound =350 m//s )

A sound source is moving with speed 50 m//s towards a fixed observer. Frequency observed by observer is 1000Hz . Find out apparent frequency observed by observer when source is moving away from observer (Speed of sound =350 m//s )

Statement 1: Sound waves can not propagate through vacuum but light waves can. Statement 2: Sound wave can not be polarised but light waves can be.

A : Doppler's effect in sound is asymmetric but in light , it is symmetric R : In Sound , change in frequency depends on the individual velocity of both the source as well as the observer . In light , change in frequency depends on the relative velocity between source and observer .

A source of sound with frequency 256 Hz is moving with a velocity V towards a wall and an observer is stationary between the source and the wall. When the observer is between the source and the wall he will hear beats.
