What is the name of the effect when light changes direction?
Reflection-when light change the direction of motion within same medium. Refraction-change of direction when moving to another medium.
What is the name for a change in direction of a wave when it passes from one medium into another?
refraction
What is the name for a change in the direction of a wave when it passes one medium into another?
refraction
The change in direction of a wave as it changes speedmovingfrom one medium into another?
It is called refraction.
What does it mean if a wave refracts?
It means that when it changes from one medium (substance) to another, there is a change of direction.
What is the refractive index of a substance?
It is the extent of the change in the direction of light as it passes from one transparent medium to another.
When waves change speed when moving from one medium to another?
Then, if they don't arrive from the direction perpendicular to the interface, they are refracted.
What is the main principal of lens?
Lenses are based on refraction - the change of direction of rays of light, when they change from one medium to another, such as from air to glass.
What is the refraction of sound?
Being a wave, sound can change its direction if it goes from one medium to another - for example, from air to water.
When waves travel from one point to another what is transferred through the medium?
When waves travel from one point to another energy is transferred through the medium. Waves are periodic vibrations or oscillations in a medium that propagate through the medium carrying energy in the form of the movement. Exceptions to this are light and gravity waves, which do not require a medium for propagation.
What indicates how much a medium can change the direction of light?
It is indicated by the refractive index of the medium.
What is it called when a wave goes from one medium to another and it changes speed and direction?
The change in direction is called refraction.
