16. a wave has a frequency of 25 hz and a wavelength of 4 m. calculate the speed of the wave

Speed of wave = 100 meter per sec

Step-by-step explanation:

Given that,

Frequency of wave = 25 Hz

wavelength of wave = 4 meter

now, as we know that,

Speed of wave = Frequency of wave × wavelength of wave

So, speed of wave = 25 Hz ×  4 m

Hence the speed of wave = 100 meter per sec     Answer

assuming you mean addition: addition and subtraction are reverse operations.

step-by-step explanation:
