How do you calculate wavelength from wavenumber?

Wave number=1/Wavelength=> Wavelength= 1/wave number


What characteristic of an electromagnetic wave is associated with the energy of that radiation?

The wavelength, E = hc/wavelength.


A wave of electromagnetic radiation has more energy if it?

... shorter in wavelength.


Seven forms of electromagnetic radiation?

The seven forms of electromagnetic radiation are: radio waves, microwaves, infrared radiation, visible light, ultraviolet radiation, X-rays, and gamma rays. Each form has different wavelengths and energies, which determine their respective uses and effects on matter.


Do light wave frequencies determine what color you see?

No, the wavelength determines the color of the light. 700nm corresponds to red, 400nm to about purple, and in between are the rest of the visible colours.


Radiation wavelength becomes longer what happens?

In Electromagnetic radiation when the wavelength increases the energy transmitted by the wave decreases. E=hf where h is a constant and f is the frequency.


What type of wave has the shortest wavelength GHz or MHz?

Usually gamma radiation are among the shortest energy wavelength.


The wave length is 670 nm what is the freguency of the radiation?

Use wavelength = frequency/300 000 with wavelength in metres and transpose.


Is a microwave?

A short-wavelength radio wave. An electromagnetic wave that is somewhere in between regular radio waves and infrared radiation.


Which wavelength would ensure that that radiation of that wavelength would be a radio wave?

Any length longer than 1 millimeter would.


What does it mean for something to have wavelike properties?

Waves are characterized by wavelength, frequency, and speed. Wavelength is the distance between two consecutive peaks or troughs in a wave. The frequency is defined as the number of waves (cycles) per second that pass a given space. Since all types of electromagnetic radiation travel at the speed of light, short-wavelength radiation must have a high frequency and long-wavelength radiation must have a low frequency.


What is a wavelength?

The distance between consecutive crests of a wave. This serves as a unit of measure of electromagnetic radiation.
