Question

Calculate the energy of photon of sodium light of wavelength 5.826×10^(-16) m in joule?​

Answer 1

approximately

135.9×10^(-3) joules

Answer 2

Answer:

3.4*10-¹⁰ Joules

Explanation:

Given - Wavelength

Find - Energy

Solution - Energy may be calculated via way of means of the system -

E = planck's constant*velocity of mild/wavelength

Planck's constant = 6.6*10-³⁴ Joules second

Speed of mild = 3*10⁸ m/s

Wavelength = 5.862*10-¹⁶ m

Keep the values in system to locate the electricity of photon.

Energy = 6.6*10-³⁴*3*10⁸/5.862*10-¹⁶

Energy = 1.98*10-²⁵/5.862*10-¹⁶

Energy = 3.4*10-¹⁰ Joules

Hence, the electricity of photon of sodium mild is 3.4*10-¹⁰ Joules .

wavelength* frequency = c

5.86x10-10 m* frequency = 3x108m/s

frequency = 3x108/5.86x10-10 s-1

= 0.512x1018 s-1

E=hv

= 6.626x10-34 * 0.512x1018

= 3.392x10-sixteen J
