The teal line of the hydrogen emission spectrum has a wavelength of 486.0 nm. A hydrogen emission spectrum has a violet, a blue, a teal, and a red line. Calculate the energy of one photon of this light.

The correct answer to the following question will be "4.08 × 10⁻¹⁹ Joule".

Explanation:

Given:

Wavelength, λ = 486.0 nm

As we know,

On putting the estimated values, we get

⇒          

⇒          

∴ 1 ev = 1.6 × 10⁻¹⁹ J

Now,

Energy,

⇒
