What is the speed of infrared rays?

Infra red is (relative to light) lower frequency/longer wavelength but it travels just as fast - the speed of light: about 300 000 000 meters per second (three hundred million).


What is 300pa?

300 pa typically stands for "per annum," which means "per year" in finance. This notation is commonly used to indicate an annual rate or frequency of something occurring over a year.


Which is the same for both red light and blue light?

Red light and blue light both travel at 300 000 000 m/s (300 000 km/s) They have different wavelengths (and thus different frequencies) with red light having the longest wavelength and smallest frequency. Blue light carries more energy than red light


Why is the statement speed of light is 300 million miles per second is not always correct?

The statement "speed of light is 300 million miles per second" is not correct because the actual speed of light in a vacuum is about 186,282 miles per second, not 300 million. The confusion may arise from approximating the speed of light to a more easily understandable number but it is important to use the accurate value in scientific calculations and discussions.


What is Millimeter waves?

Millimetre waves are Extremely High Frequency (EHF) electromagnetic waves with wavelengths in the millimetre range.EHF frequencies are from 30 GHz (30 000 MHz) to 300 GHz (300 000 MHz), and EHF is considered the highest radio frequency band - above this, electromagnetic radiation is considered to be infra-red.
