What is Refracting and Reflecting?
Reflection: light bounces off of a surface, like a mirror.Refraction: light goes through a substance and bends. For example, white light through a prism comes out in a rainbow because the light is refracted or bent and each color has a different index of refraction.
What is it called when light that can travel through something?
Objects that allow most light to pass through are described as transparent. In contrast, translucent objects allow some light to pass through, but don't let you see objects. Opaque objects allow no light to pass through.
Whats the difference between reflection and refraction?
Reflection is when a wave comes into contact with something and then returns to the medium from which it came. Refraction is when direction of a wave changes due to a change in it's phase velocity. For example, when light goes through a window, it refracts, but you can slightly see yourself in it, because a fraction of the light also reflects. Another example, I'll use an arrow. If the arrow goes this way ------> and then hits a wall and comes back this way and bounces off and goes this way, ^ it has Refracted.^^^^
What is the physical significance of refractive index?
The amount of refraction depends on the difference in density between two mediums. So, the amount of refraction a material has, or it's refraction index, is the amount light will bend as it goes from medium into another medium. For instance, Vacuum is considered to have a refraction index of 1 and all other materials being denser than vacuum will naturally have a larger refraction index, they bend light more. So, it simply means that- since the object has a high density it will slow down light by a greater amount.
Where is the speed of light greater than the speed of light in water?
The speed of light through vacuum is constant. The speed of light through air is slightly less. The speed of light through water or some other medium is even less than that. The factor by which the speed of light (and its wavelength) is reduced within a medium is called the "index of refraction" (which determines the amount of bending that occurs when light goes from one medium to another).
How does light go through a lens?
Light goes in the lens, refraction occurs, and the light exits the lens.
What do you call when light goes through prism and comes out the other end it starts with re?
refraction

A light ray goes from air into acrylic block is the angle of refraction larger or the angle of incidence?
The angle of refraction is larger. BOOBIES

Light travel fastest in?
a vacuum (space is pretty much a vacuum). It slows down when it goes through gas, even more through water, glass or diamond (causing refraction or bending of the light).
Differntiate between reflection of light and refraction of light?
when light hits an object...for example a mirror..it"ll bounce back(reflection) but when light goes into a new middel...for example from air to water it'll cahnge directions and the speed of light may also change ( that's refraction)
