Question

calculate the value of an Einstein corresponding to radiation of 6000angstrom wavelength​

Answer 1

Explanation:

v=cλ

c=3×108ms−1,λ=6000Å=6000×10−

v=3×108ms−16000×10−10m=5×104s−1

h=6.625×10−34Js,v=5×1014s−1

E=6.625×10−34Js×5×1014s−1=3.3125

Answer 2

Question - Calculate the frequency and energy of a photon of radiation having a wavelength 6000 angstrom

Given - Wavelength

Find - Frequency and energy

Solution - Frequency is 5*10¹⁶ centimetres/second and energy is 33*10-¹¹ erg.

The formula to calculate frequency and energy is - E = hf

Further, frequency is given by the formula -

c = f * wavelength

We know, the speed of light or c is 3*10⁸ m/s.

Wavelength in metres = 6*10-⁷ metres or 6*10-⁸ centimetres

Frequency = 3*10⁸/(6*10-⁷)

Frequency = 5*10¹⁴ metre/second or 5*10¹⁶ centimetres/second

The value of h is 6.6*10-²⁷ erg sec

E = h*f

E = 6.6*10-²⁷*5*10¹⁶

E = 33*10-¹¹ erg

Thus, frequency is 5*10¹⁶ centimetres/second and energy is 33*10-¹¹ erg.
