TV signals broadcast by a Delhi studio cannot be directly received at Patna, which is about 1000 km away. But the same signal goes some 36000 km away to a satellite, gets reflected and is then received at Patna. Explain.
Q2
Can we perform Young's double slit experiment with sound waves? To get a reasonable "fringe pattern", what should be the order of separation between the slits? How can the bright fringes and the dark fringes be detected in this case?
Q3
Is it necessary to have two waves of equal intensity to study interference pattern? Will there be an effect on clarity if the waves have unequal intensity?

Young's double slit experiment can be performed with sound waves, as the sound waves also show interference pattern. To get a reasonable "fringe pattern", the separation of the slits should be of the order of the wavelength of the sound waves used.In this experiment, the bright and dark fringes can be detected by measuring the intensity of sound using a microphone or any other detector.

The unstretched length of the cord is 3 ft, and the radius of the semicircle is r = 2 ft. The block is released from rest at A. Neglect the size of the block. What is the angle that the block leaves the surface? (If you are unable to solve the final equation for θ, clearly state the 1-equation 1-unknown for partial credit.)
