What are two things that can reflect light?
mirror and glass
What would you see if a white light passed through 2 prisms?
Well, since the light passed through, I think we can assume that these prisms are transparent. You said white light passed through two prisms, so I guess it was incident at 90 degrees, and the sides of the prisms were parallel. You would not necessarily see anything, unless (1) you were looking and (2) you were looking at the correct place- i.e. the light was shining in your eye, or reflecting off something you can see. If I was blind, I would see nothing.
What do you understand by the term reflection of light . Name two objects which can reflect light?
mirror
What is the ability of an object to reflect light?
To bounce back light is called to reflect light. light reflection is of two types-regular and irregular reflection.
What are the kinds of reflections?
the two ways in which a surface can reflect light are regular reflection and diffuse reflection.
What are the use of prisms in telescopes?
Two triangular prisms are used in the design of a periscope to reflect the incoming light rays at 90 degree angles. They are first reflected down periscope, then again towards the eye.
What happens when light passes through two erect prisms?
a good time
Principle of light of a periscope use to work?
A periscope works on the principle of total internal reflection of light. Made with the help of two right angle prisms, the principle can be observed at the prisms' back face.
What happens when you pass white light through two prisms which are kept erect?
your ugly mum
What happens when light is passed through two similar prisms placed in inverted position?
It is spread out into a spectrum, then recombined into white light.
What happens if two inverted prisms are placed one behind another?
dispersion of light doesn't occur.

How are prisms named?
Prisms consist of two polygonal "bases" and rectangular faces joining them. Prisms are named after the polygonal bases.
Do all prisms have two prisms?
No, each prism is ONE prism. By definition!
Can two moons reflect off each other?
Yes. Any two surfaces that reflects light can reflect off each other. They must have a light source though like a sun.
