Answer:
λ = 521nm
Explanation:
To convert wavelength to frequency we need to use the equation:
ν = c / λ
Where ν is frequency: 5.76x10¹⁴s⁻¹;
c is speed of light: 3x10⁸ms⁻¹;
And λ is wavelength in m:
Wavelength is:
λ = c / ν
λ = 3x10⁸ms⁻¹ / 5.76x10¹⁴s⁻¹
λ = 5.21x10⁻⁷m
= 521nm
The wavelength of a photon of green light that has a frequency (v) of 5.76x10¹⁴ s-¹ is 5.21 × 10-⁷m
HOW TO CALCULATE WAVELENGTH:
- The wavelength of a photon can be calculated by using the formula below:
λ = v/f
Where;
- λ = wavelength of the photon (m)
- v = velocity (3 × 10⁸ m/s)
- v = frequency of photon (s-¹)
- According to this question, the frequency (v) of a greenlight is 5.76x10¹⁴ s-¹, the wavelength can be calculated as follows:
λ = 3 × 10⁸ ÷ 5.76 x 10¹⁴
λ = 3/5.76 × 10⁸-¹⁴
λ = 0.521 × 10-⁶
λ = 5.21 × 10-⁷m
- Therefore, the wavelength of a photon of green light that has a frequency (v) of 5.76x10¹⁴ s-¹ is 5.21 × 10-⁷m.
