How reflected light can be reflected again?
Reflected Light can be Reflected Again When two mirrors are placed opposite to each other, the first mirror reflects light that falls on its surface. The periscope makes use of this concept by using two plane mirrors. Periscopes are used in submarines, tanks and also by soldiers in bunkers to see things outside.
What is use of periscope Class 8?
By using a periscope, we can see the objects on the other side of a high wall which cannot be seen by us directly. The periscope makes use of two plane mirrors to see over the top of things. A periscope works on the reflection of light from two plane mirrors arranged parallel to one another.
Why is periscope used?
A periscope lets you look around walls, corners or other obstacles. A periscope is a useful example of the law of reflection at work. It’s important that your mirrors are placed at a 45° angle, because light always reflects away from a mirror at the same angle that it hits it.
Which type of mirror is used in Periscope?
plane mirrors
What is the main principle behind periscope?
It works on the principle of simple reflection. Light from the object is reflected by a series of mirrors inclined at a certain angle which allows it to reach the observer bypassing obstacles that may have been present in a straight line path from the object to the observer.
What is periscope on which phenomenon it is based?
reflection
Which light phenomenon takes place in Periscope?
Reflection of light
Which of the following is a natural phenomenon which is caused by?
Solution. A rainbow is a natural phenomenon caused by the dispersion of sunlight in the sky.
What are the conditions for total internal refraction?
TIR only takes place when both of the following two conditions are met: the light is in the more dense medium and approaching the less dense medium. the angle of incidence is greater than the so-called critical angle.
