1. A hydrogen gas is contained inside a glass tube. When a bright light is
illuminated, the spectrum showed an absorption line at 654 nm.
What is the energy of the absorbed photon?​

Explanation:

The energy of a photon : 2.96.10⁻¹⁹ J

Further explanation

The photoelectric effect is an electron coming out of a metal because of electromagnetic radiation

One type of electromagnetic radiation is light

Electrons can come out of metal because they absorb electromagnetic energy radiated on metals. There is also kinetic energy released from metal, which is according to the equation:

\large {\boxed {\bold {E = hf-hfo}}}

E=hf−hfo

fo = the threshold frequency of electromagnetic waves

Radiation energy is absorbed by photons

The energy in one photon can be formulated as

\rm E = h \times fE=h×f

Where

E = energy of light, J
