Light is a form of radiation.
Radiation is an emanation of energy from a body, that can pass through a vacuum unaffected. it travels in a straight line, and is only slightly affected by gravity. A black hole obviously will, with its massive gravity well, affect all forms of light and radiation.
Heat, light particles (photons) and radiation particles (alpha, beta, and gamma) are all forms of radiation, among other more exotic forms.

What happens if an LED is connected wrong?
It will be reverse biased and will not light.
How can you calculate speed of radar?
Radar emissions are electromagnetic radiation that travel at the speed of light.
The distance to go marker light is connected to the what size isolation transformer?
45
Name two electromagnetic wave use to carry through an optical fiber?
We usually use some form of coherent light wave in fiber optic conduits to move data. That means a laser and the emission of light somewhere at or about optical wavelengths.
What components do you need to make a simple series circuit to light on bulb?
You need a Battery, Light Bulb, Ammeter, Switch.
Do all light waves emit radiation?
Light waves do not emit radiation, light waves are radiation.
Is radiation the same as light?
Light is one form of radiation. There are others.
Why is it necessary to detect radiation from space and not just light?
Light is radiation.
How is visible light and electromagnetic radiation different?
They are not different.Visible light IS electromagnetic radiation.
What is light classified as?
Light is an electromagnetic radiation. Our eyes are sensitive, the E/M radiation at the light wavelength. Hence we see light. The E/M radiation adjacent to light are Infra-red(IR) and Ultra-violet(UV), which we do not see.
What makes a light bulb an example of radiation?
The luminous radiation emitted by the light bulb.
What are the welding safety hazards?
Safety hazards connected with welding include heat, bright light, ultraviolet radiation and fire, as well as inhalation of toxic metal fumes.
Light from a star is a form of?
Electromagnetic radiation.
What form of radiation can humans see?
Humans can see visible light, which is a form of electromagnetic radiation with wavelengths between 400-700 nanometers. This range of wavelengths is detected by the photoreceptor cells in our eyes and processed by the brain to produce the sensation of sight.
What radiation is the light bulb?
Light, heat, and a very small amount of electromagnetic field.
What are the three radiation that comes from the sun?
Ultraviolet Radiation,Visible Light,Infared Radiation
What does radiation have to do with the speed of light?
All forms of electromagnetic radiation move from place to place at the speed of light.
