Since water is a substance of higher refractive index than air, therefore then speed of light decreases as it enters water.

Why do electromagnetic waves travel at the speed of light?
Radio-waves, like light, are electromagnetic waves and hence travel at the speed of light.
Which property do all electromagnetic waves have in vacuums?
All electromagnetic waves travel at the speed of light in a vacuum.
Can macnetic waves travel at the speed of ligth?
Light is an electromagnetic wave. Electromagnetic waves travel at the speed of light. Electric and magnetic waves don't travel on their own - the wave travels as a combined electric and magnetic wave.
Heat waves traveling at the speed of light are called?
Heat waves traveling at the speed of light are called RADIATION! :)
IS electromagnetic waves travel faster than speed of light?
Electromagnetic waves are, by definition, light. So they travel at the exact same speed as light.Also, a "Do" would be appropriate here, instead of an "IS".
What is it that all electromagnetic waves do the same?
All electromagnetic waves travel at the same speed in a vacuum -- the speed of light.
How do you know the speed of an electromagnetic wave in a vacuum?
The speed of electromagnetic waves in a vacuum is the same as the speed of light (which is, in itself an electromagnetic wave). It can be measured by finding the frequency and wavelength of two different waves, and then by that correlation, the speed of the waveform.
Electromagnetic waves may exist at?
Electromagnetic waves can exist only at one speed.
How are water waves different from electromagnetic waves?
electromagnetic waves can travel through vacuum while water waves travel in water.
The speed of an electromagnetic wave is?
In a vacuum, all electromagnetic waves have the same speed: about 300,000 kilometers per second.In a vacuum, all electromagnetic waves have the same speed: about 300,000 kilometers per second.In a vacuum, all electromagnetic waves have the same speed: about 300,000 kilometers per second.In a vacuum, all electromagnetic waves have the same speed: about 300,000 kilometers per second.
Why do electromagnetic waves travel at the speed of light?
Radio-waves, like light, are electromagnetic waves and hence travel at the speed of light.
What happens when transverse electromagnetic waves encounter cavity?
light waves or electromagnetic waves are transverse and sound waves are longitudinal
How do you know the speed of an electromagnetic wave in vacuum?
The speed of electromagnetic waves in a vacuum is the same as the speed of light (which is, in itself an electromagnetic wave). It can be measured by finding the frequency and wavelength of two different waves, and then by that correlation, the speed of the waveform.

Which property do all electromagnetic waves have in vacuums?
All electromagnetic waves travel at the speed of light in a vacuum.
Is water waves a electromagnetic wave?
No, water waves are mechanical waves.
What does contrast electromagnetic waves with water and sound waves mean?
It means explain how electromagnetic waves are different than water and sound waves.
