2018年3月30日 · Use the wave equation v=f\\lambda This is a very important equation in physics and works for all types of waves, not just electromagnetic ones. It works for sound waves too, for example. v is the velocity f is the frequency \\lambda is the wavelength Now, when we're working with the electromagnetic spectrum, velocity v is always the speed of light. The speed of light is …

2015年5月1日 · Gamma Radiation has the shortest wavelength. Order is as follows (shortest to longest wavelength): Gamma, X-Rays, UV, Visible, Infrared, Microwaves, Radio Waves. Gamma has the shortest wavelength because it has a higher frequency, meaning more waves in a second than any other radiation, which results in the short wavelength. Frequency is inversely …

Electricity and magnetism can be static, but when they move together they make waves. Electromagnetic waves are formed when an electric field couples with a magnetic field. The magnetic and electric fields of an electromagnetic wave are perpendicular to each other and to the direction of the wave. Light, microwaves, x-rays, and TV and radio transmissions are all kinds …

2016年11月28日 · Frequency and wavelength are inversely proportional. Notice in the diagram below that as wavelength decreases, the frequency increases. The speed of light, c is a constant, so when wavelength decreases, frequency increases and vice versa.

2018年3月17日 · Energy increases as the wavength decreases and the frequency increases. Long wavelength, low frequency waves, such as radio wave seas are thought to be harmless. They don’t carry much energy and are therefore considered safe by most people. As the wavelength decreases and frequency increases, the energy increases - for example X-rays …

2014年8月9日 · The equation that relates wavelength, frequency, and speed of light is c = lambda*nu c = 3.00xx10^8 "m/s" (the speed of light in a vacuum) lambda = wavelength in meters nu = frequency in Hertz (Hz) or 1/"s" or "s"^(-1)". So basically the wavelength times the frequency of an electromagnetic wave equals the speed of light. FYI, lambda is the Greek letter lambda , …

2016年2月7日 · Three things change: frequency, wavelength and method of production. The electromagnetic spectrum is a family of waves that have the same essential nature (they are vibrations in electric and magnetic fields) but different wavelength/frequency and in some cases a different method of production. The spectrum is often represented by a continuous sinusoidal …

2014年10月11日 · Electromagnetic radiation is made up of waves that are composed of photons which travel at the speed of light, c, in a vacuum, which is exactly 299,792,458 m/s, usually rounded to three significant figures as "3.00" x "10"^(8)"m/s". Ask your instructor for his or her preference. All electromagnetic waves have wavelength and frequency. The wavelength is the …

2017年8月30日 · The wavelength lamda and frequency nu for any wave is related by the equation, lamdanu=v where v is the wave velocity. For all electromagnetic waves, v=c and hence, lamdanu=c is the relationship, where c is the speed of light in vacuum. When light travels in some medium the velocity changes and for frequency nu constant (which is a fixed characteristic of …

2014年7月15日 · To calculate the wavelength of a radio wave, you will be using the equation: Speed of a wave = wavelength X frequency. Since radio waves are electromagnetic waves and travel at 2.997 X 10^8 meters/second, then you will need to know the frequency of the radio wave. If the radio wave is on an FM station, these are in Megahertz. A megahertz is one million …
