The intensity of a beam can be measured by the power contained in a square metre cross-section of the beam. For example the Sun's light has an intensity of about 1400 watts per square metre.

What type of wave is EM radiation?
Electromagnetic radiation consists of waves that are composed of oscillating electric and magnetic fields and do not require a medium to propagate. This type of wave is considered a transverse wave, with electric and magnetic fields perpendicular to the direction of propagation.
What happens when you increase electromagnetic wave?
To increase the intensity, if that's what you mean, more energy is required. That would also mean that the electromagnetic wave carries more energy.
What is the highest frequency part of EM spectrum?
That's the gamma radiation.
How Does the EM radiation plays significant roles in our life and why?
For example:* We use visible light to see * We use microwave radiation in a microwave oven * We use various types of electromagnetic waves for communication * The Sun's energy comes to us, mainly via EM radiation.
Define radiation?
EM radiation higher in frequency than violet visible light but lower in frequency than soft x-rays.
What are spectrographs?
Spectrographs are instruments that separate EM radiation (primarily light) into a spectrum of frequencies and record the data. The intensity of radiation at the different frequencies can be used to ascertain information about the source of the radiation or the material through which it is passing.
What does electromagnetic have to do with EM radiation?
EM is short for electromagnetic.
What type of wave is EM radiation?
Electromagnetic radiation consists of waves that are composed of oscillating electric and magnetic fields and do not require a medium to propagate. This type of wave is considered a transverse wave, with electric and magnetic fields perpendicular to the direction of propagation.
At what speed does all EM radiation travel at?
In a vacuum, 3x10^8 ms^-1. Basically the speed of light, it is EM radiation afterall.
What type of em radiation do conventional ovens use?
infrared radiation ;)<3
What type of em radiation has shortest wavelength and most energy?
Gamma radiation
What is the scientific term for light?
"electro-magnetic radiation" "electro magnetic radiation" em radiation
What distance does electromagnetic radiation travel in 10.7?
In 10.7 femtoseconds, em radiation will travel 3.208 E -6 meters. EM radiation travels at the speed of light, or 299, 792, 458 m/s.
From Where does the energy carried by an EM wave come?
The electromagnetic (EM) spectrum is a name for different types of radiation. Most radiation comes from the sun. Want more info?
What equipment to use to measure wavelength?
A spectrophotometer or a spectrometer can be used to measure the wavelength of light. These instruments disperse light into its different wavelengths and can accurately determine the wavelength of a particular light source.
What EM radiation that can be seen with the naked eye?
Visible light
What type of em wave raditiation is a type of heat wave?
Heat radiation is mainly associated with infrared radiation.
