Question

calculate the wave number frequency of radiation having wavelength 3000A° λ = 3000×10-10​

Answer 1

Ans: Frequency (ν) = C/λ (wave length)

= (3*108 meters/sec)/(3000*10-10 meters)

= 1015 sec-1

Energy = hν

= (6.63*10-34 Joule.Sec). 1015 sec-1

Energy = 6.63*10-19 Joule

Explanation:

please give thanks

Answer 2

For the given wave the frequency, υ=c/λ
