Question

What is the frequency of the wave if it travels at 1500cm/s

Answer 1

Answer:

Step-by-step explanation:

we know that velocity = distance/ time;

Velocity of wave is given;

Velocity = 1500 cm/ 1 sec ;

Distance travel by the wave is 1500 cm;

frequency = c/ wavelength = 3*10^8/1500 = 0.2 *10^4 = 200 kHz

Because 1kHz= 1000Hz
