Question

calculate the wave number frequency of radiation having wavelength 3000A°​

Answer 1

Given wavelength =3000A ∘

E=hν

c=hν

v= λc

E=h.λc

=6.626 x 10 −34 ×3000 × 10 −93 × 10 8

=6.626 x 10 −910 8

=6.626 x 10 −34X 108 X 10 7=6.626 x 10 −34 X 1015

E= 6.626 x 10 −34 X 10 19Joules.

Frequency (ν) = C/λ (wave length)

Frequency (ν) = C/λ (wave length)= (3*108 meters/sec)/(3000*10-10 meters)

Frequency (ν) = C/λ (wave length)= (3*108 meters/sec)/(3000*10-10 meters)= 1015 sec-1

Frequency (ν) = C/λ (wave length)= (3*108 meters/sec)/(3000*10-10 meters)= 1015 sec-1Energy = hν

Frequency (ν) = C/λ (wave length)= (3*108 meters/sec)/(3000*10-10 meters)= 1015 sec-1Energy = hν= (6.63*10-34 Joule.Sec). 1015 sec-1

Frequency (ν) = C/λ (wave length)= (3*108 meters/sec)/(3000*10-10 meters)= 1015 sec-1Energy = hν= (6.63*10-34 Joule.Sec). 1015 sec-1Energy = 6.63*10-19 Joule
