What is a characteristics of a mechanical wave?
They need a medium to propagate through.
Why don't light waves need a medium?
Light wave flows as a form of radiation. One of the basic characteristics of radiant energy is it don't need a medium. But If it flows through a medium, it won't raise the temperature of medium.
Is MDF a conductor or a insulator?
If you mean medium-density fibreboard, then it's an insulator. However, it's exact characteristics vary.
What does light waves do when it moves from one medium to another?
A light wave can slow down or speed up when it enters another medium. Since the speed of wave motion in general depends on characteristics of the environment, you can always expect the speed of a wave to change as it moves from one medium to another. In the case of sound, it's the mechanical characteristics that matter, whereas for light and other electromagnetic waves, the determining characteristics are the electrical ones. So the speed of light changes when it enters a different medium. Now, since the product of (frequency) x (wavelength) is the wave speed, and the frequency can't change, we notice that if the speed changes, then the wavelength also changes in a new medium. Furthermore, right at the interface ... the boundary between the two media ... if the light doesn't hit the boundary exactly perpendicular to it, then we say that the light is "refracted" at the boundary, meaning that the light leaves the boundary in the new medium in a different direction compared to its direction in the previous medium.
What are characteristics of refraction?
1. When a ray of light travels obliquely from an optically rarer medium to an optically denser medium,it bends towards the normal at the point of incidence. in this case,angle of incidence is greater than the angle of refraction...

What are the characteristics of a common emitter amplifier?
There are a number of characteristics found in a common emitter amplifier. Not only are the parameters considered, but also their performance. Characteristics and performance are: voltage gain/ medium; current gain/ medium; power gain/ high; input / output phase relationship/ 180 degrees; input resistance/ medium; and output resistance/ medium.

What the most characteristics of good medium of exchange?

Is the speed of light in a medium affected by the velocity of the light as it enters a new medium?
No. The speed of light is determined by the electrical characteristics of the medium it's in, regardless of what medium it came from or what medium it's headed for when it leaves this one.
What is a characteristics of a solution?
Solutions consist of a solvent, a liquid medium into which solutes can dissolve.
Why don't light waves need a medium?
Light wave flows as a form of radiation. One of the basic characteristics of radiant energy is it don't need a medium. But If it flows through a medium, it won't raise the temperature of medium.
Why speed of light is constant in vaccum?
Because the speed of light is determined by the electrical characteristics of the medium, and the electrical characteristics of vacuum don't change.
What are characteristics of a wood?
Characteristics of a wood are things such as the woods texture, color, and density. For example the characteristics of cherry wood would be rich color, smooth texture, with a fine grain, and a medium weight.
What is the formula to find the speed?
There are a few different formulas, depending on what measurements you know. For mechanical waves . . . the mechanical characteristics of the medium. For electromagnetic waves . . . the electrical characteristics of the medium. For all waves . . . the product of (wavelength) multiplied by (frequency).
