Why an exssecively thin film appears black in the reflection of light?
Destructive interference. If the sheet is very thin, near half the wavelength of the incident light then light reflected from the top layer is out of phase with light reflected from the bottom layer. These two reflected light waves will cancel each other out.
What is produce an image by manipulating light within a layer of liquid crytal cells.?
display
What is reflection and refraction of light?
Reflectivity isn't a property of light, it's a property of the surface that reflects the light. It is the proportion of the energy in an incoming light beam which when it hits the surface is reflected rather than absorbed.
One difference between reflection and refraction of light waves is that?
reflection is when light its something like a mirror and refraction is light going through something solid that is not like a mirror when light falls on a surface and bounces back, it is reflection and when light is absorbed by the surface or passes through the surface but does not bounces back, it is refraction.
How coherent light can be produced without reflection and refraction?
i dont know but can we see without reflection?
What prevents light from scatering within the eye?
The Choroid.
When a beam of light undergoes diffuse reflection do the individual rays within the beam follow the law of reflection?
Yes.
What tunic of the eye prevents light scattering within the eye?
choroid
Reflection is when light what?
Reflections occur when light bounces of a smooth and shiny surface. Glass mirrors have a thin layer of silver on the back so that light is reflected.
Why albino people should avoid looking at bright light?
The lack of pigment in the eye of albino leads to hyper-Photosensitive. The absence of melanin pigment in the choroid layer of the eye causes internal reflection of light within the eyeball resulting in blurred vision.
What is the cause of a rainbow?
The reflection (normally twice) of light within a droplet of water and back to your eye.
What is a cause of rainbows?
The reflection (normally twice) of light within a droplet of water and back to your eye.
What is the bouncing of light off an object?
Reflection
Can you see reflection without light why?
no reflection basically deals with light rays. so there is no reflection withou light.
Why an exssecively thin film appears black in the reflection of light?

What is diffusing reflection?
When the rays of light do not follow the laws of reflection, then this type of reflection is called diffused reflection.
One difference between reflection and refaction of light waves is the?
In reflection, the light waves travel within the same media and maintains the same speed but in refraction light waves travel through a different media and so their speed changes.
