How do the light waves coming from the pencil change speeds?
when the pencil enters the water
How the appearance of the pencil and the change in speed of the light waves relate?
They are related by Hamda+A its also related by transferring waves to the cup thats fill with water so yeah like it?
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 waves travel the fastest?
The light wave, which is electromagnetic energy, is the fastest wave. The speed of light, which is a physics constant, is the speed of light in a vacuum, and no object with mass can be accelerated to this speed.
Heat waves traveling at the speed of light are called?
Heat waves traveling at the speed of light are called RADIATION! :)

When do light waves change speed?
speed of light is different for materials of different refractive index and also higher the refractive index lesser will be speed of light in that medium. so if light travels from rarer to denser medium (with respect to refractive index) then light waves will change their speed
What property of light waves can be observed as light waves pass from one medium to another and change speed?
diffraction
What is the speed of gravitiy?
Gravitational waves propagate at the speed of light. Any change in the distribution of masses will propagate at that speed.
What property of light waves pass from one medium to another and change speed?
Refraction.
Which travels at a greater speed light waves or sound waves?
Light Waves.
If light waves change speed as they pass from one medium into another at an angle the light will be?
Refracting
Do radio waves travel at the speed of sound at the speed of light or at some speed in between?
'Radio' waves are physically and electrically identical to light waves except for their frequency (wavelength), and they travel at the same speed as light does.
Is this true Light waves do not change speed as they travel from air through water?
no. they slow down.
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.
What is it called when waves change there speed when they go in to different matereals?
This is related to a change in direction. The change in direction is called refraction. The numbers that describe HOW MUCH the speed of the wave slows down is called "index of refraction", especially in the case of light waves.
