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.

Why are the insides of binoculars and cameras are painted black?
To prevent internal reflection
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.
Why if you paint the inside of a box white and cut a hole to see inside it it appears black?
It appears black because you're blocking the only source of light; the hole you cut; in and out of the box. Therefore, it is completely dark inside.
Which thing is dark more then night?
A Black Hole. Night is darker than day, but there is still artificial light and the light of celestial bodies. However, light cannot escape a black hole in space, so the area occupied by a black hole appears darker than night.
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.
Do black and white a color?
No black and white are just the reflection of the light
Why sunlight turn black colour into white?
Sunlight cannot turn black into white. However, a black surface may appear white in bright sunlight due to reflection of all the wavelengths of light from a shiny surface. The color black is actually the result of the absence of reflection of any wavelengths of light while the color white is the result of reflection of all the wavelengths of light.
Are black and white a color?
Yes. White is produced by the reflection of all colored light, and black is produced by the absorption of all colored light.
Why does a crack in a window pane sometimes appears silvery?
this is due to total internal reflection and wave theory of light.
What colour will blue be in a green light?
Blue what ? ! ? Do you mean an object that appears blue in white light ? Such an object appears black in green light.
What is the color associated with reflection?
White. Black absorbs all colors of the light spectrum and thats why it feels hot and looks black. White objects reflect all forms of light, therefore they are cooler in sunlight. An objects color is determined by what color of light it reflects. Since white is all the colors combined, if a substance reflects all the colors then it appears white. If another substance absorbs every color except for 1 shade of red, then the substance will appear that exact shade of red that it reflects.
What is the bouncing of light off an object?
Reflection
What appears when all the colors is absorbed by the object?
When light of all colors (wavelengths) is absorbed by an object, the object appears black.
Can you see reflection without light why?
no reflection basically deals with light rays. so there is no reflection withou 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.
How is the moon able to give off light?
Light from the moon is a reflection of light from the sun, the moon only appears to give off light because its reflective lunar dust the reflects liight from the sun
