Distinguish between light waves and sound waves.
A radio station broadcasts at 800 KHz. If the radio waves (em-waves) travel with a speed of 3 × 108 m/s, what will be the wavelength of the wave?
If you are walking on the moon surface, can you hear the cracking sound behind you? Explain.
Frequency is the most fundamental property of a wave. Why?
We can't hear echo in a small room. Why?
Distinguish between progressive waves and stationary waves.
How are stationary waves formed?
Can longitudinal wave be polarized? Explain.
How do transverse waves differ from longitudinal waves?
A plane progressive wave equation in given by \(y=0.2\sin\left(512\mathrm{πt}-\frac{25}8\mathrm{πx}\right)\) where y is in centimeters, x in meters and t in seconds. What is the speed of the wave?
What are stationary waves?
