The noise of a car horn.
Glass, clear plastics, perspex, most gases
mechanical waves need a medium to travel through, electromagnetic waves do not. Electromagnetic waves can travel through space, mechanical waves can not.:PElectromagnetic waves do not require a medium, but mechanical waves do.
No, smoke is not considered a transparent medium because it does not transmit rays of light through it. An example of a transparent medium would be glass.
Some of the light is reflected off the glass at the same angle - in a manner and angle similar to that of a ball deflected off a surface at a similar angle. This is what happens when light reflects from car windows into our faces. Much of the light, however, will penetrate the glass, so that the light source is seen from the other side. Nevertheless, on contact with the glass, the light that penetrates will be refracted (bent) and travel through the glass at a different angle from that of its original contact with the glass; but once having travelled through the glass, it will leave at its original angle of contact. The amount of refraction depends on a number of factors, but especially, on the thickness of the glass and specific angle of contact involved. So, the light bends as it passes through the glass, but leaves at its original angle.
There are 2 energy changes that take place in this action: Mechanical to Light Energy and Mechanical to Electrical Energy. To explain further, when a generator, which uses mechanical energy, is used in turn to light up the bicycle lamp, the light emitted is light energy. At the same time, when the generator lights up the bicycle lamp, the lamp is light up using electrical energy, so mechanical energy also transformed into electrical energy. ===============================> heat and light (in the light bulb)

No. Sound and ocean waves are.
No. Light is an example of an electromagnetic wave, which can travel through a vacuum. Mechanical waves must travel through a medium, and cannot travel through a vacuum.
No, light waves is an example of Electro Magnetic waves
When light is refracted, it means that it is redirected to another direction. A good example is when a light ray hits a glass and it redirected by the glass to a different object.
For example, air, water, glass.
Glass, clear plastics, perspex, most gases
Light refracts when the light photons changes medium, such as from air into glass. A curved glass surface will result in different levels of refractions and hence the different colors.
Non mechanical waves are Eletro magnetic waves. We can devide 2 waves. 1 is mechanical waves & 2 is electromagnetic waves. For example Sound is a mechanical wave & Light is an electromagnetic wave.
Light is not mechanical energy but it can be transformed into mechanical energy. Light creates an impact as it hits a surface.
A spark, such as a flint-lock rifle. Over-used brakes.
first of all we need to know What is transparent?Transparent is transmitting light; able to be seen through with clarity.For example clear glass, water, clear plastic, Acrylic sheet, light, air... that's all I can think of so far.
