Does electromagnetic radiation create light?

Electromagnetic (EM) radiation is a form of energy that is all around us and takes many forms, such as radio waves, microwaves, X-rays and gamma rays. Sunlight is also a form of EM energy, but visible light is only a small portion of the EM spectrum, which contains a broad range of electromagnetic wavelengths.

What determines the wavelength of light?

The wavelength of the light can be calculated using this formula dsinθ = nλ. Where lambda (λ) represents the wavelength of light, n is the order of the interference spot, d is the separation distance between the slits in the grating, and θ is the angle between the central maximum and the bright spot in question.

How are the wavelength and frequency of electromagnetic radiation related?

Wavelength and frequency are inversely proportional to each other: wavelength × frequency = constant. Their product is equal to the velocity (λf = c). This relation is true of all kinds of wave motion, including sound, although for sound the velocity is about a million times less.

How is EM wave produced and propagated?

The spark current oscillates at a frequency (ν), which is a characteristic of the circuit. The changing magnetic field, in turn, induces an electric field so that a series of electrical and magnetic oscillations combine to produce a formation that propagates as an electromagnetic wave.

What can be determined from a wavelength?

The properties of light we can determine from the wavelength are the frequency and Energy – however, observing the source of the wavelength does lead to a host of other information.

How is the wavelength of radiation related to the energy of the photons of the radiation?

The amount of energy is directly proportional to the photon’s electromagnetic frequency and thus, equivalently, is inversely proportional to the wavelength. The higher the photon’s frequency, the higher its energy. Equivalently, the longer the photon’s wavelength, the lower its energy.

How is the wavelength of light related to its frequency?

Frequency and wavelength have both direct and inverse relationships. For instance, if two waves are traveling at the same speed, they are inversely related. The wave with shorter wavelength will have a higher frequency while a longer wavelength will have a lower frequency.
