Are speed of light and the frequency of light the same thing?

Question

I need to know if it is or isn't and the reason why or why not.

Answer 1

Speed and frequency are two different things.

 

Speed refers to the distance covered in a set amount of time. In general the speed of light, for example, is 300,000,000 m/s, meaning that every second it travels about 300,000,000 meters! That is a little less than the distance from the earth to the moon, or about seven times around the earth.

 

The units for speed vary, but are always some distance per unit time. In the above example, we used meters per second, but it could be miles per hour, kilometers per minute, feet per day (for molasses in winter), etc.

 

Frequency refers to the cycles per set amount (or unit) of time. For example, frequencies of light, radio waves and electricity are often referred to in terms of "Hertz." One Hertz (usually written as hz) means one cycle per second. This is a VERY low frequency. The sounds that we hear are usually between about 50 and 15,000 Hz. The higher the frequency, the higher the pitch. Visible light ranges from 430-790 THz (which means terahertz, or 1000000000000 Hz). In other words, light is very high frequency! Different frequencies of light appear to us as different colors.

 

Another answer mentioned something about intensity. Intensity is different from both speed and frequency. Intensity is the power of the light, electricity or sound, and is measured in different ways. The more powerful or intense the light, the brighter it will appear. Very intense lights (e.g., lasers) heat surfaces and can even cut through or vaporize materials.

Answer 2

The are not the same.  Speed of light is how fast light travels at a certain distance.  Frequency of light has to do with the intensity of the light. 

 

Also, the units for these quantities differ.  Speed of light is meters per second.  Frequency of light is hertz.
