- visible light from a candle.
- x-rays from an x-ray machine.
- alpha particles emitted from the radioactive decay of uranium.
- sound waves from your stereo.

What are the two examples of radiation?
- Radio waves.
- Microwaves.
- Visible light.
- Infrared light.
- Light from the sun.
- Lasers.
What is another example of radiation?
Examples of Radiation
Radiation includes emanation of any portion of the electromagnetic spectrum, plus it includes the release of particles. Examples include:
A burning candle emits radiation in the form of heat and light
. The Sun emits radiation in the form of light, heat, and particles.
What is an everyday example of radiation?
Some common examples of Radiation are
Ultraviolet light from the sun
, heat from a stove burner, visible light from a candle, x-rays from an x-ray machine. All life on Earth depends on the transfer of energy from the Sun, and this energy is transferred to the Earth over empty space.
What is an example of radiation heat?
The heating of the Earth by the Sun
is an example of transfer of energy by radiation. The heating of a room by an open-hearth fireplace is another example. The flames, coals, and hot bricks radiate heat directly to the objects in the room with little of this heat being absorbed by the intervening air.
What are 4 examples of radiation?
- ultraviolet light from the sun.
- heat from a stove burner.
- visible light from a candle.
- x-rays from an x-ray machine.
- alpha particles emitted from the radioactive decay of uranium.
- sound waves from your stereo.
- microwaves from a microwave oven.
- electromagnetic radiation from your cell phone.
Is TV an example of radiation?
Television, too,
emits radiations
. The old television sets emit x-ray waves which can easily be absorbed by the human body, and is harmful as well. However, modern TV sets use Liquid Crystal Displays (LCD) or Plasma Displays which are not only less harmful than the older sets but are also incapable of producing x-rays.
What are 4 examples of convection?

- Boiling Water. Convection comes into play while boiling water. …
- Blood Circulation in Warm-Blooded Mammals. …
- Air-Conditioner. …
- Radiator. …

What household items use radiation?
- Radon Seeping Into The Basement. …
- Granite Countertops Could Emit Low Levels of Radiation. …
- Check for Radioactive Elements in Ceramics. …
- Drinking Glasses That Contain Uranium. …
- Glow in the Dark Clocks or Watches With Radium in the Paint. …
- Old Box Shaped Television May Emit X-Ray Radiation.
What is radiation in Class 11 example?
Land breeze and see-breeze are formed due to convection. (iii) Radiation The
process of heat transmission
in the form electromagnetic waves, is called radiation. Radiation do not require any medium for propagation. It propagates without heating the intervening medium.
What are 3 sources of radiation?
- Cosmic Radiation.
- Terrestrial Radiation.
- Internal Radiation.
What are the three types of natural radiation?
The three most common types of radiation are
alpha particles, beta particles, and gamma rays
. Alpha radiation is not able to penetrate skin.
What are the five sources of radiation?
- Natural background radiation. Cosmic radiation. Terrestrial radiation. Inhalation. Ingestion.
- Artificial sources of radiation. Atmospheric testing. Medical sources. Industrial sources. Nuclear fuel cycle.
Is all heat radiation?
Radiation happens when heat moves as energy waves, called infrared waves, directly from its source to something else. This is how the heat from the Sun gets to Earth. In fact,
all hot things radiate heat to cooler things
. … Infrared waves are part of a spectrum of energy waves known as the electromagnetic spectrum.
What is the best example of heat transfer through radiation?
Heat transfer by radiation occurs when microwaves, infrared radiation, visible light, or another form of electromagnetic radiation is emitted or absorbed. An obvious example is
the warming of the Earth by the Sun
. A less obvious example is thermal radiation from the human body.
Is all radiation hot?
The intensity of such energy flux depends upon the temperature of the body and the nature of its surface [3].
The radiation occurs at all temperatures
, with the rate of emission increasing with the temperature. Figure 3.1. Heat transfer by thermal radiation between two bodies.
