Yes, light can have a single wavelength. A laser generates a coherent beam of light. It's all one frequency, i.e., it's all the same wavelength.
This ray has a definite wavelength.
Monochromatic light is light of one wavelength. E.g. A red laser has one single wavelength and is therefore categorised as 'monochromatic light'. A standard light bulb emits light of many different wavelengths across the visible spectrum and therefore is not 'monochromatic light'.
The longest wavelength / lowest frequency visible light is the red end of the spectrum. The shortest wavelength / highest frequency visible light is the violet end of the spectrum.
Red is the longest wavelength of visible light
A photon's color is determined by its wavelength, which corresponds to a specific color in the visible spectrum. A photon of shorter wavelength appears bluer while a longer wavelength appears redder. The perception of color in photons is a result of how our eyes detect and interpret different wavelengths of light.
At a single wavelength, it is called monochromatic
Monochromatic light is the term used to describe light of a single wavelength. It consists of only one color and does not contain multiple wavelengths.
Monochromaticity refers to the purity of a single wavelength in light or other electromagnetic radiation. A monochromatic source emits light at a single specific wavelength without any other wavelengths present.

Monochromatic light is light of one wavelength. E.g. A red laser has one single wavelength and is therefore categorised as 'monochromatic light'. A standard light bulb emits light of many different wavelengths across the visible spectrum and therefore is not 'monochromatic light'.
A spectral line
The laser light is the type of light that only has one wavelength in its phase. Coherent light is light that has a single frequency and wavelength, and can be described with a single wave equation.
Monochromatic light is light composed of a single wavelength. One example of monochromatic light is the laser, which emits light of a very specific color or wavelength, making it highly monochromatic.
A laser produces light of only one color because it emits a single wavelength of light. This is achieved by the specific properties of the laser medium and the optical resonator within the laser cavity that amplifies a specific wavelength. As a result, laser light is highly monochromatic, meaning it consists of a single color or wavelength.
The ionization energy of a rubidium atom is about 403 nm. Therefore, the maximum wavelength of light required to ionize a single rubidium atom would be higher than 403 nm.
The relationship between frequency (f), wavelength (λ), and the speed of light (c) is given by the formula: c = f * λ. This equation states that the speed of light is equal to the frequency of the wave multiplied by its wavelength.
I don't think so. Coherence is defined for light of a single wavelength.
