Question

Each element emits its own unique wavelength of light which can be used to determine the identity of that element. The packet or light wave emitted is called a

Answer 1

Photon

Step-by-step explanation:

The simplest description of a photon is to consider it as a bundle of electromagnetic energy.

In the context of wave - particle duality, light is considered sometimes as a particle. Each bundle of the particles of light wave is called a photon of light.

The wavelength of a photon of light emitted by an element can be used as a tool to identify that particular element.
