What is the Speed of light travelling through transparent material?
The speed of light when traveling through transparent materials is slower than in a vacuum. This is due to interactions with the atoms within the material. The speed of light is determined by the refractive index of the material, which is a measure of how much the speed is reduced compared to a vacuum.
Why are electromagnetic waves sometimes called electromagnetic radiation?
because it is the method of translocating energy that has been called radiation.Radiation is a term that refers to the radius of a sphere meaning that it goes out (propagates) in all three spatial directions equally.
What equation is used to determine speed of light through material?
The equation used to determine the speed of light in a given material is v = c / n, where v is the speed of light in the material, c is the speed of light in a vacuum, and n is the refractive index of the material.
Why there is no sound year like light year?
The velocity of light in vacuum is a universal constant. A light year is the distance travelled at that velocity in one year. To define a sound year it would be necessary to also specify the precise characteristics of material it is being propagated through. A vacuum won't do, since sound doesn't travel through a vacuum.
How does the speed of light compare in water glass and diamond?

What is the materials index of refraction?
It's (the speed of light in vacuum)/(the speed of light in the material) .
What is the method by which the wave travels through a medium or vacuum?
Waves disturb or perturb the medium and this propagates the wave.
How does light travel when it travels through material that doesn't change?
When light travels through a material that doesn't change, it propagates in a straight line at a constant speed. The speed of light may be slightly slower in the material compared to a vacuum, depending on the material's refractive index, but the overall path of light remains linear.
How does vacuum travel sound?
Sound is carried by vibrations moving through a material, whether the material is solid, liquid or gaseous. A vacuum is the absence of material and therefore there is no material to vibrate, hence no sound can be passed through a vacuum.
What is the direction of propagation of light in a vacuum?
Light in a vacuum propagates in a straight line in all directions.
What is speed of light in more refractive index?
The speed of light in a material with a higher refractive index is slower compared to its speed in a vacuum. This is due to the interaction of light with the atoms and molecules in the material, causing it to bend or slow down as it propagates through the medium.
What is the materials through which a wave travels?
Sound waves can travel through any material, but not through a VACUUM. You may be thinking of the term "MEDIUM", which is often used GENERICALLY to signify what a 'Wave" is traveling through. -------------------------------------------------- The material is called "matter".
Does electromagnetic energy need something to travel through?
No, electromagnetic energy can travel through a vacuum. It propagates through space as electric and magnetic fields that oscillate in a perpendicular fashion.
The denser the medium through which it is traveling the slower a what wave propagates?
Electromagnetic wave, namely, light as it travels through denser medium its speed decreases from its speed when it travels through air or vacuum.
Does light travels slowest through space?
As the medium through which light propagates in space is closes to a vacuum, light propagates very well in space. However, it travels at the same speed as it would on earth, as light travels at 299,792,458m/s in a vacuum, regardless of where that vacuum is located. the light travels in same speed whether it travels in space or earth.
What of a material indicates how much the speed of light in the materials changes as light passes through?
The property of a material that indicates how much the speed of light changes as it passes through is called the material's refractive index. This index is a measure of how much the speed of light is reduced in a material compared to its speed in a vacuum. The higher the refractive index, the more the speed of light is reduced in that material.
Does sound pass through vacuum?
No, sound cannot pass through a vacuum because sound requires a medium, such as air, water, or a solid material, to travel through. In a vacuum, there are no particles for sound waves to propagate through, so they cannot travel.
