Question

You are given the wave y (x,t) = -5 cos (3x+2t)

where all quantities are in SI. This wave propagates to the ___________________ and has angular frequency _________________.

a. left; 3 Hz

b. right; 3 Hz

c. None of the other choices is correct.

d. right; 2 Hz

e. left; 2 Hz

Answer 1

Answer #1

As there is plus sign between 3x and 2t so wave is propagates toward left.

The coefficient of time is give the angular frequency , from equation it is 2.

So angular frequency is 2Hz.

Correct option is (e)

Answer 2
