When a wave passes from a less dense medium to a more dense medium what might change?
Velocity (speed and direction) Wavelength (frequency)
A change in speed of a wave as it enter a new medium produced a change in?
wavelength
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.
When light wave change its medium from dense to rare frequency increases or decreases?
Frequency doesn't change in the transition between media. Speed changes, with a consequent changein wavelength. In passing to a less-dense medium, speed and wavelength both increase.
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.
When a light wave enters into a medium of different optical density?
index of refraction ( or refractive index)
In what situation does a wave not change its direction when it passes from one medium into another?
Waves only change direction when they intersect the other medium at an incident angle of other than 90o
Will the speed of a wave change if you increase its frequency while in the same medium?
The speed of the wave depends on characteristics of the medium. Changing thefrequency results in a change in wavelength, just enough so that the product of(frequency) times (wavelength) is always the same number . . . the speed.
Is wavelength and frequency vary inversly?
The speed at which a wave propagates is the product of its wavelength and its frequency. The wavelength and the frequency vary inversely because the speed of a certain type of wave in a certain type of medium under certain conditions is constant.
What is the change of direction when a wave enters a different medium called?
Refraction
What happens when a wave changes medium?
On passing from one medium to another, the frequency of any wave stays constant. The wavelength changes such that the new wavelength equals the old wavelength multiplied by the old refractive index divided by the new refractive index. Lnew = Lold x (Nold/Nnew) Where L is the wavelength and N is the refractive index. The refractive index is a property related to wave velocity, which will vary in different mediums.
