How does wavelengths of light differ from other waves?

Answer 1

If we restrict ourselves to electromagnetic waves, the answer is simple.

The very narrow wavelength band of electromagnetic radiation that we call "light" is the only one that we can SEE. All other electromagnetic radiation is invisible to us, though occasionally we can feel its effects: infrared heats our skin, ultraviolet burns, and other electromagnetic waves can cause cancer or heat our food when they are microwaved.

The main difference between wavelengths of light and other types of waves is their frequency and speed. Light waves are electromagnetic waves that travel at the speed of light and have frequencies within the visible spectrum. Other waves, such as sound waves or water waves, are mechanical waves that require a medium to travel through and have different frequencies and speeds.

When evaluating a one-sided limit, you need to be careful when a quantity is approaching zero since its sign is different depending on which way it is approaching zero from. Let us look at some examples.
