Explanation

Bremsstrahlung or braking radiation is an example of a continuous spectrum.

The spectrum of Bremsstrahlung radiation is continuous

Because the energy of the emitted photons can vary continuously depending on the degree of deceleration of the charged particles.

This leads to a continuous range of wavelengths or frequencies in the emitted radiation, forming a continuous spectrum.

Bremsstrahlung radiation is commonly encountered in X-ray tubes

Where high-energy electrons are decelerated by a target material

Producing X-rays with a continuous spectrum of energies
