(A) Refraction from mirrors
(B) Reflection from mirrors
(C) Diffraction from mirrors
(D) Deviation from mirrors

Answer 1

Hint: Just recall your early childhood, when someone handed you a kaleidoscope and asked you to look inside. Kaleidoscope is a low-tech device which can create a never-ending array of beautiful art and sometimes it's breathtaking. Here we will define all the given four terms and then decide the correct answer.

Complete answer:
The slight bending of the light when it passes around the edge of an object is due to the diffraction. For example – Light Entering and bending around the corners of the doors and windows.
The phenomenon of splitting one light into the components of colourful lights is known as the dispersion of the light. For Example: Rainbow during the rainy-season and when light is passed through prism it splits into rainbow like structure.
The reflection of light is the change in the direction of the wave-front between the two different mediums. For Example – When you keep a pencil in a glass of water it seems to be broken or two parts of the pencil inside the water and outside the water appear in the bending form.
Colourful patterns are formed due to which the reflection is caused by the mirrors in which they are placed at sixty degrees in the kaleidoscope.
Hence, option B is the correct answer.

Note:
Always go through all the options and its terminology to solve these types of word statement questions. Gradually know the difference between all the given options and then accordingly justify the correct answer. Refraction and reflection are two different terminologies.
