Question

The periodic wave in the diagram below has a frequency of 40 hertz. What
is the speed of the wave?

answers:
A. 120 m/s
B. 60 m/s
C. 27 m/s
D. 13 m/s

Answer 1

Answer:

60. m/s

60 m/s is the answer i hope this helps pls give me the brainliest

Answer 2

The speed of the wave will be 60 m/sec. The speed of the wave is wavelength and frequency.

What is frequency?

Frequency is defined as the number of repetitions of a wave occurring wave in 1 second.

The given data in the problem is;

The frequency of periodic wave is,f=  40 hertz

The wavelength of the wave is,$\lambda = 1.5 \ m$

The speed of the wave is,v

The speed of the wave is;

$\rm v = \lambda \times f \\\\\ \rm v = 1.5\times 40 \\\\\ v= 60 \ m/sec$

Hence, the speed of the wave will be 60 m/sec.
