Question

Please give answer fast....... the wavelength of electromagnetic wave in 600 angrestrom then what will be its frequency???

Answer 1

Frequency is the number of wave tops passes in one second

And if the speed of light is 300,000,000 meters per second, then the number of tops passes is (3*10 ^8 ÷ 6*10^-7 )

= 5 * 10 ^ (14) Hz

500,000,000,000,000

tops passes per second
