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 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
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 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.
Where do the light waves change speed from a pencil?
ACTUALLY ! Its when the pencil enters the water .
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 are waves that travel through space at the speed of light called?
All electromagnetic waves travel through space at the "speed of light". Light is one form of electromagnetic waves.
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.
Light waves change speed and directions when they pass from one transparent material into another This is called?
refraction
