Question

the ratio of frequency of 2 mechanical wave in a medium is 5 :7 find the ratio of their, a-wavelength, b- time period

Answer 1

a)7:5 because frequency and wavelength are inversely proportional
frequency = speed of light/wavelength
b) 7:5 because T=1/frequecy

Answer 2

Answer:

hope it helps you

plese mark as brainlest and give thanks

ANS)        a)7:5 because frequency and wavelength are inversely proportional

frequency = speed of light/wavelength

b) 7:5 because T=1/frequecy
