Find the ratio of the wavelengths corresponding to the frequencies `v_(1)=7.35 xx 10^(-14)s^(-1)` and `v_(2)=4.47 xx 10^(14)s^(-1)` in case of electromagnetic radiations.

Explanation

For an electromagnetic radiation,
`lambda=(c)/(v) prop (1)/(v) " " :. " " (lambda_(1))/(lambda_(2))=(v_(2))/(v_(1)) " "` (`:'` c is constant)
According to the available data , `v_(1)=7.35xx10^(14)s^(-1)` and `v_(2)=4.47 xx 10^(14)s^(-1)`
`(lambda_(1))/(lambda_(2))=((4.47 xx 10^(14)s^(-1)))/((7.35 xx 10^(14 )s^(-1)))=0.61`
