Question

The is a picture of a CD il ated by a candle. The CD is essentially behaving like a diffraction grating What is diffraction? ? This phenomenon occurs when two waves overia but their amplitudes are opposite o, each other resulting at a least a partial cancellation. This phenomenon is used headphones. O The bending of waves around small obstacles. Thus, when waves pass through small openings they will spread out. Interference patterns and colorful rainbow-like displays are often the result O The pheno enon in which the speed of a wave depends on the frequency of the wave. In prisms, this results in white light being spread out according to the individual frequencies present. O The act of a wave bouncing off of a new medium that it encounters. This phenomenon is often used to make rooms look larger than they are. O The act of a wave passing m O The compl from one medium to another. Often the wave is deflected as a result. This is why swimming pools do not look as deep as they actually are. ete reflection of light off of a surface because the incident angle (the angle which the light strikes the surface) is greater than the critical angle. For angles less than the critical angle, some of the light is refracted and some is reflected. Fiber optics make use of thi

Explanation / Answer

diffraction is bending of light around corners or bending around small obstacles. due to bending constructive and destructive phases are formed so it gives colourful view.

so 2nd option is correct
