What property of light waves can be observed as it passes from one medium to another and change speed?
Devilishbabe2011
When light travels from one medium to another, the speed changes according to the index of refraction.
Explanation:
The speed of light is different in each different medium. Only in a vacuum does it reach its natural speed of 300,000 kilometers/second.
We assign the speed of light in a vacuum the letter c.
c=300,000 kilometers/second.
Every medium which transmits light is characterized by a quantity called the index of refraction.
We assign the index of refraction the letter n.
n=index
of refraction.
n is different for every different material and always greater than 1.
The speed of light in a material is given by v=c
/n.
Velocity equals the speed of light in a vacuum divided by the index of refraction of the material.
The speed of light in a material is always slower than in a vacuum.
When light travels from one medium to another, the speed changes according to the index of refraction.

What property of light waves pass from one medium to another and change speed?
Refraction.
Which property of light will change when the medium of propagation changes?
The speed.
How does energy and speed relate?
The speed of a wave is a property of the medium, changing the speed would need a change in the medium itself. If the medium doesn't change as a wave moves, the wave speed is steady. Formula: Speed = distance divided by time
When waves travel from one medium to another what does not change?
The character frequency would never change
When Waves are moving from one medium to another do they change speed?
Yes, WAVE motion is slowed by the higher Density of the Medium.

The speed.
When light travels from 1 medium to another what will change?
Its velocity will change
If sim medium was used for motility determination for Proteus vulgaris what noticeable change to the medium will be observed?
It will turn black in the inoculation stab as well as throughout the medium because P. vulgaris is a flagellated and motile organism.

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
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
