7. Determine the wavelength for a photon of light
with a frequency of 6.15 x 10Hz.

Number 6&7 in the pic

Answer 1

6) λ = 0.84 × 10⁻⁸ m

7) λ = 0.84 × 10⁻⁶ m

Step-by-step explanation:

6) Given data:

Wavelength of photon = ?

Frequency of photon = 3.56 × 10¹⁶ Hz

Solution:

Formula:

Speed of radiation = frequency × wavelength

c = speed of wave = 3×10⁸ m/s

by putting values,

3×10⁸ m/s = 3.56 × 10¹⁶ Hz × λ

λ = 3×10⁸ m/s / 3.56 × 10¹⁶ s⁻¹

λ = 0.84 × 10⁻⁸ m

7) Given data:

Wavelength of photon = ?

Frequency of photon = 6.15 × 10¹⁴ Hz

Solution:

Formula:

Speed of radiation = frequency × wavelength

c = speed of wave = 3×10⁸ m/s

by putting values,

3×10⁸ m/s = 6.15 × 10¹⁴ Hz × λ

λ = 3×10⁸ m/s / 6.15 × 10¹⁴ Hz s⁻¹

λ = 0.84 × 10⁻⁶ m
