Ultraviolet light occurs just above the range of electromagnetc radiation that is detectable by the human eye and has a shorter wavelength than violet. This means it has a higher frequency since all light waves are presumed to travell at the same speed, whether visible to us or not.
To explain this in simple terms, if two trains are travelling at the same speed, and one has short cars and the other has long cars, the one with the short cars will pass by us more cars per minute than the one with the long cars. This is called frequency...the number of times something happens in a given time frame.
velocity of light= frequency of light *wavelength of light
therefore wavelength =(3*10^8)/fequency
The wavelength of light times the frequency of light is its speed, which is close to 2.9979*108 m/s in most mediums.
Radio waves have much lower frequency / much greater wavelength than visible light has.
Wavelength is speed / frequency.
very nice answer.
No, red is the longest wavelength of visible light, with the lowest frequency and the least energy. Violet light has the shortest wavelenght, with the highest frequency and the most energy (of visible light).
Frequency. f=c/l Where, f=Frequency, l=Wavelength and c=Velocity of light in free space.
There are several ways to calculate the frequency of light emitted or absorbed by different chemicals, and they depend on what you already know. For example, if you know the energy of the particle, then you can calculate frequency from E = planck's constant x frequency and solve for frequency. If you happen to know the wavelength, then you can use C = wavelength x frequency and solve for frequency (where C = speed of light).
Shortest wavelength means the highest frequency, meaning the photons have the highest energy. That is color violet. The violet light colors the skin brown. Red light with lower energy photons cannot do that.
very nice answer.
-- Red light has the lowest frequency of those three. -- Green light has lower frequency than violet light has. -- The wavelength of all light is inversely proportional to its frequency.
Its wavelength (or frequency).
The wavelength of an X-ray is much shorter than the wavelength of a red light from a neon sign. The frequency is much longer in an X-ray than the frequency of a red light from a neon sign.
... greater wavelength, lower frequency, less energy per photon.
Visible light has a higher frequency, a higher energy per photon, and a smaller wavelength, compared to infrared.
wavelength = c/frequency of light where c is the speed of light.
wavelength = speed of light/frequency so we rearrange frequency = speed of light/wavelength Hopefully you can figure it out from here...
Wavelength times frequency is the speed. To know the wavelength, you have to divide the speed by the frequency of the light.
Light with a lower frequency will have a longer wavelength. Frequency and wavelength are inversely proportional to each other (i.e. as one increases, the other decreases and vice-a-versa). The product of frequency and wavelength is the speed of light.
Wavelength times frequency is the speed. To know the wavelength, you have to divide the speed by the frequency of the light.
To find (wavelength): Divide (speed) by (frequency). To find (frequency): Divide (speed) by (wavelength).
