Question

At any point, the intensity of a wave is a) proportional to the square of the wave amplitude b) proportional to the square of the wave frequency c) proportional to the inverse square of frequency d) both (a) and (b) e) none. To produce standing waves in a string, you need to fix its ends between two posts. (T/F) True False Velocity of sound in a solid medium is (a) directly proportional to the squareroot of the medium's bulk modulu b) inversely proportional to the squareroot of the medium's density c) directly proportional to the medium's density d) both a) and b) e) none Sound waves are transverse. (T/F) True False In a longitudinal wave, particles of the medium oscillate perpendicular to the direction of wave propagation. (T/F) True False

Explanation / Answer

1. I is directly propotional to the A^2 , w^2 and v.
