The magnitude of the incident angle with the normal of the reflection surface and reflection angle with the normal of the surface are the same. The direction of the reflection is away form the surface and the incident is toward the surface.

What is the difference Radiation and irradiation?
Radiation is emitted from something and travels from its point of origin to somewhere else. When radiation hits something else (and is therefore stopped) the thing that has been hit is said to have been irradiated. Thus a sunbather is undergoing irradiation by radiation emitted by the sun.
Write a sentence using the word emitted?
The bomb emitted radiation.
How does Longitudinal waves detect the position of an object?
The Doppler effect is used in radar to provide information regarding the speed of moving targets by measuring the frequency shift between the emitted and the reflected radiation. A transmitter produces pulsed radio frequency radiation. It is fed to a movable aerial from which it is transmitted as a beam. When the beam strikes the moving vehicle a part of the energy of the radiation is reflected back to the aerial. Signals received by the aerial are passed to the receiver, where they are amplified and detected. There will be a shift in frequency of the reflected wave and emitted wave due to the Doppler effect. The apparent frequency of the reflected wave is given by F = f ( 1 - v/c ) where v is the speed at which the source and the observer are moving apart and c is the speed of electromagnetic radiation, f is the real frequency or the frequency of the emitted signal The output of the detector is usually displayed on a cathode ray tube. The apparent frequency is measured and thus the speed of the vehicle is calculated. A heterodyne device may also be used in which beats are produced by superimposing the emitted radio wave over the reflected (from the vehicle) radio wave. In the heterodyne wave meter, a variable frequency local oscillator is adjusted to give predetermined beat frequency with the incoming reflected wave, enabling the frequency of the reflected wave which has had Doppler shift to be determined. Thus the speed of the vehicle can be determined.
What happens when an unstable nucleus undergoes radioactive decay?
Particles or electromagnetic radiation are emitted.
Definition of radiation?
The definition of radiation is when energy is emitted as particles or waves.
How does the radiation emitted from the sun differ from the radiation emitted by earth?
In fact, radiations are reflected by earth but not emitted.
How do you watch weather from space?
There are weather sattellites that orbit the Earth that can detect reflected radiation, emitted radiation, or radiation reflected only by water vapour as well as satellites that emit microwave radiation to detect the clouds or precipitation.
Why there is a difference in absorbed and emitted radiation in equatorial and polar areas?
There is a difference between poles and equator. It is because depletion is minimum at equator.
Which biome has the highest net radiation budget value?
It's actually the rain forest because that is the biome closest to the equator, meaning that it has a net radiation budget surplus (more solar radiation is absorbed than reflected/re-emitted as infrared radiation), unlike the biomes closer to the poles which will have a net radiation budget deficit (more infrared radiation is re-emitted/reflected than solar radiation that is absorbed).

Would you sense reflected or emitted electromagnetic radiation when measuring the temperature of the ocean's surface?
If you were to measure reflected radiation then you would be measuring the temperature of the source of light (the sun)! So you need to look at the emmited radiation (measured during the night) to guage the temperature of the ocean's surface.
In what form is radiant energy reflected back into space?
Energy is re-radiated by the Earth as infrared (thermal) radiation.

Is synchrotron radiation emitted perpendicular to the circular path of the electrons?
Yes, synchrotron radiation is emitted perpendicular to the circular path of the electrons. This is because the radiation is generated when the electrons are deflected, or accelerated, due to the magnetic field in the synchrotron. The emitted radiation is tangential to the circular path, resulting in a perpendicular radiation pattern.
What is the difference between spontaneous emission of radiation and stimulated emission of radiation?
The laser causes the stimulated emission of radiation. The light emitted is monochromatic and coherent,that is plane polarised. I imagine that spontaneous emission occurs in a Light emitting diode ,monochromatic but not polarised. Hope this is of help
18) The amount of radiation that an individual absorbs depends on?
On the amount of radiation emitted; on how close the individual is to the source of the radiation; on any objects in between which might absorb part of the radiation.
Is landsat 7 passive?
Landsat 7 is the Enhanced Thematic Mapper Plus (ETM+). ETM+ is a passive sensor that measures solar radiation that is either reflected or emitted.
