## Which of the following has minimum wavelength?

Out of the given wavelengths gamma rays have the minimum wavelength and infrared rays have the maximum wavelength.

## What is the wavelength of a electromagnetic wave?

Electromagnetic waves are categorized according to their frequency f or, equivalently, according to their wavelength λ = c/f. Visible light has a wavelength range from ~400 nm to ~700 nm. … Electromagnetic waves with shorter wavelengths and higher frequencies include ultraviolet light, X-rays, and gamma rays.

## Which Colour has minimum frequency?

red light has maximum wavelength and violet has minimum wavelength.As the frequencyandwavelengthof a wave are inversely proportional to each other so,red lighthas minimum frequency and violet light has maximum frequency. Moreover, violet light has maximum energy andred lighthas minimum energy.

## Which is not electromagnetic wave?

Beta rays are not electromagnetic waves because they are charged particles and are capable of getting deflected by the magnetic field. These rays are not pure energy as a photon.

## How do you find a wavelength?

Wavelength can be calculated using the following formula: wavelength = wave velocity/frequency. Wavelength usually is expressed in units of meters. The symbol for wavelength is the Greek lambda λ, so λ = v/f.
