### What is a low frequency wave?

Radio waves are the lowest frequency waves. Next are microwaves, then infra-red waves.

### Infra red frequency Hz?

10 Tera hertz to 400 Tera hertz.

### How green house gasese are the more or less problem than carbon dioxide?

Greenhouse gasses are called that because they are opaque to low frequency infra-red, but transparent to high frequency infra-red. Thus the sun's heat, which is high frequency infra-red, can penetrate to the earth's surface, which warms up and emits low frequency infra-red, which is trapped in the atmosphere. This makes the atmosphere act like a greenhouse by trapping heat. There are a number of such gasses, such as metahane and carbon-dioxide. This is a highly controversial subject since the leading "sceintist" studying the matter was caught fabricating data.

### Does ultraviolet light have a lower frequency than visible light?

No, "infra" means below, "ultra" means above. Infra red light is below red and ultra violet is above violet light.

### What is the release of energy from the sun?

Electromagnetic radiation in the infra red, visible, and ultra violet frequency ranges

### How is heat tranferred by radiation?

First of all it is important to note that heat and infra-red rays are NOT the same thing. When an object gets really hot it starts to glow, emitting red light at first, (hence the phrase: 'red hot') because red is the least frequency. Hotter objects emit light of higher frequency. A light bulb and the Sun are both examples of this. But infra-red rays are even lower in frequency than red light. Infra-red rays are emitted in the same way by objects at room temperature. That means you, your computer and everything around you are 'glowing' with this infra-red radiation. Infra-red rays carry energy between objects at the speed of light. This process causes relatively hot objects to cool down faster.

### Which colour has the minimum frequency?

Of the colors of visible light, that would be red. Note that there are electromagnetic waves with an even lower frequency - for example, infrared - but those are not visible to human eyes.

### What are the infra red radiation sources?

Anything that has a temperature emits IR radiation. Hotter things emit more at a higher frequency. Then they become Red.

### What has a longer wave length a infrared radiation or red light?

Infrared radiation has a lower frequency and longer wavelength than red light. Note that "infra" means "below" in this case referring to the lower frequency.
