thin films of soap sometime display an array of colours. this display is the result of: a) reflection, diffraction, and interference b) reflection, refraction, and interference c) reflection, refraction, and polarization d) refraction, interference, and polarization e) reflection, interference, and polarization

Respuesta :

The array of colors observed when viewing films of soap are caused by the interference, and from the reflections of light from two nearby surfaces (outer surface and inner surface). Among the choices, the closest answer would be B. reflection, refraction, and interference.

Answer:

b) reflection, refraction, and interference

Explanation:

When light incident on thin soap film then due to the change on medium a part of the light will reflect from the interface of the soap film and then remaining light will go into other medium.

This phenomenon of transferring light to other medium is known as refraction of light. Now this part of light will again go for interference when it incident on the next interface.

So again we will have some light reflected from that part and the remaining part will go out into air

So here in that case the reflected light from two parts of the thin soap film will show interference due to which we will get the colors.

so here all the phenomenon of light that is observed in the thin film is given as

b) reflection, refraction, and interference
