in infra red region of the spectrum of h a line is obtained have wave

1.	in infra red region of the spectrum of h a line is obtained have wave no:3802cm inverse.calculate the wavelength and frequency
Answer» ANSWER: 52.279 x 10-28 J Explanation: We know that , FREQUENCY(v) can be calculated as follows: λv = C where λ = 3802 x 10-2 m c = 3 x 108 m/s Frequency, v = (3 x 108 m/s) / 3802 x 10-2m = 7.89 x 106 s-1 Energy = hv where h = 6.626 x 10-34 J/s Hence, energy of the photon = 6.626 x 10-34 J/s x 7.89 x 106 s-1 = 52.279 x 10-28 J

Answer»

52.279 x 10-28 J

Explanation:

We know that ,

FREQUENCY(v) can be calculated as follows:

λv = C

where λ = 3802 x 10-2 m

c = 3 x 108 m/s

Frequency, v = (3 x 108 m/s) / 3802 x 10-2m

= 7.89 x 106 s-1

Energy = hv

where h = 6.626 x 10-34 J/s

Hence, energy of the photon

= 6.626 x 10-34 J/s x 7.89 x 106 s-1

= 52.279 x 10-28 J
