# The electromagnetic waves' wavelength frequencies and energies brainly

Just as wavelength and frequency are related to light, they are also related to energy. The shorter the wavelengths and higher the frequency corresponds with greater energy. So the longer the wavelengths and lower the frequency results in lower energy. The energy equation is E = hν The energy carried by an electromagnetic wave is proportional to the frequency of the wave. The wavelength and frequency of the wave are connected via the speed of light: Electromagnetic waves are split into different categories based on their frequency (or, equivalently, on their wavelength) As a wavelength increases in size, its frequency and energy (E) decrease. From these equations you may realize that as the frequency increases, the wavelength gets shorter. As the frequency decreases, the wavelength gets longer. There are two basic types of waves: mechanical and electromagnetic 1) Electromagnetic radiation(EM ) is described in terms of it's wavelength frequency and energy .

### what is the relationship between the wavelength frequency

In the electromagnetic spectrum there are many different types of waves with varying frequencies and wavelengths. They are all related by one important equation: Any electromagnetic wave's frequency multiplied by its wavelength equals the speed of light. FREQUENCY OF OSCILLATION x WAVELENGTH = SPEED OF LIGH These properties are closely and inversely related: The larger the frequency, the smaller the wavelength — and vice versa. A third is energy, which is similar to frequency in that the higher the frequency of the light wave, the more energy it carries. Your eyes detect electromagnetic waves that are roughly the size of a virus The electromagnetic spectrum can be expressed in terms of energy, wavelength or frequency. Each way of thinking about the EM spectrum is related to the others in a precise mathematical way. Scientists represent wavelength and frequency by the Greek letters lambda (λ) and nu (ν)

Violet light has a wavelength of ~400 nm, and a frequency of ~7.5*10 14 Hz. Red light has a wavelength of ~700 nm, and a frequency of ~4.3*10 14 Hz. Visible light makes up just a small part of the full electromagnetic spectrum. Electromagnetic waves with shorter wavelengths and higher frequencies include ultraviolet light, X-rays, and gamma rays Waves with longer wavelengths have a lower frequency and carry less energy. Waves with shorter wavelengths have a higher frequency and carry more energy. Remember that: The electromagnetic spectrum includes, in order of increasing frequency and decreasing wavelength: radio waves, microwaves, infrared radiation, visible light, ultraviolet. As noted before, an electromagnetic wave has a frequency and a wavelength associated with it and travels at the speed of light, or c.The relationship among these wave characteristics can be described by v W = fλ, where v W is the propagation speed of the wave, f is the frequency, and λ is the wavelength. Here v W = c, so that for all electromagnetic waves, c = fλ

Electromagnetic radiation is characterized by a broad range of wavelengths and frequencies, each associated with a specific intensity (or amplitude) and quantity of energy. This interactive tutorial explores the relationship between frequency, wavelength, and energy, and enables the visitor to adjust the intensity of the radiation and to set. Visible red light with a wavelength of 700 nm, for example, has a frequency of 4.29 x 10 14 Hz, and an energy of 2.84 x 10 -19 J per photon or 171 kJ per mole of photons (remember Avogadro's number = 6.02 × 10 23 mol −1). The full range of electromagnetic radiation wavelengths is referred to as the electromagnetic spectrum Electromagnetic radiation behaves as waves, but also behaves as packets of energy called Photons. We can measure a photon's position and momentum. Photons have no mass, but each photon has a specific amount of energy that depends on its frequency (number of vibrations per second). Each photon has a wavelength Q. Frequency and energy have a direct relationship. This means as the frequency increases the energy. If long wavelength is equal to low frequency, and red has the LONGEST wavelength of all the colors, then RED has a high frequency. then RED has a low frequency Here are a few of them, ranged in order from the longest wavelength to the shortest.
