A flat flashlight, also known as a credit card flashlight, is a small, portable flashlight designed to be carried in a wallet or purse. Wavelength refers to the distance between two consecutive peaks or troughs in a wave of light. Even though a flashlight is flat, the light it emits is still made up of electromagnetic waves with a specific wavelength. The wavelength of light emitted by a flashlight depends on the type of bulb or LED used to produce the light.

A flashlight with a white LED produces light with a wavelength between 400 and 700 nanometers. This range of wavelengths includes all visible spectrum colors seen when light is shone through a prism. A flat flashlight emits light having a wavelength determined by the type of bulb or LED used to produce the light.
