the defects of mirrors are overcome if 45 degree right-angled glass prisms are used.the critical angel of ordinary glass is about 42 degree and a ray falling normally on face of such prism total internal reflection occurs and the ray is turned through 90 degree .examples:totally reflecting prisms replace mirrors in good periscopes,light can also be reflected through 180 degree by a prisms this happens in binoculars.

What objects have two parallelcongurent bases?
Prisms have two parallel and congruent bases. These bases are connected by rectangular or parallelogram-shaped sides, creating a three-dimensional shape. Examples of prisms include rectangular prisms, triangular prisms, and hexagonal prisms.
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 happens when light passes through 2 prisms?
When light passes through two prisms, the light is refracted twice - once when entering the first prism and again when exiting the second prism. The second refraction can result in the light changing direction a second time, depending on the orientation and properties of the prisms.
What is more effective at transmitting light mirrors or prisms?
Mirrors are generally more effective at transmitting light than prisms because they reflect light without dispersing it, maintaining the original direction and intensity. Prisms, on the other hand, refract light and can disperse it into its constituent colors, affecting the transmission of light.
What are the differences between prisms and cylinders?
Prisms have two parallel and congruent bases connected by rectangular lateral faces, while cylinders have two circular bases connected by a curved lateral surface. Prisms have flat sides and edges, while cylinders have a curved surface.
What are some names of prisms?
Prisms are named based on the shape of their bases. Common types include triangular prisms, rectangular prisms, and hexagonal prisms. Additionally, there are specialized prisms like pentagonal prisms and octagonal prisms, reflecting the number of sides in their base shapes. Each type retains the characteristic of having two parallel, congruent bases connected by rectangular lateral faces.
Is a sphere a prism and why?
No, because if you look at all the other prisms its totally different ....
What are the angles of a totally reflecting prism?
A right angled isosceles ie. a 45 - 90 - 45 degree prism is called a totally reflecting prism.
How many types of prisms are there?
There are many types of prisms such as rectangular prisms,polyganic prisms crossed prisms and etc.
When droplets of water in the atmosphere act like prisms the colors in sunlight undergo?
a phenomenon called dispersion. This causes the different wavelengths of light to separate, resulting in the formation of a rainbow. The droplets act as miniature prisms, bending and reflecting light to create the distinctive bands of colors.
What are triangler prisms and rectangler prisms?
Triangler Prisms are like chocolate bars
Why Are so Many Products Packed In Rectangular Prisms?
This is because there is no limit on rectangualar prisms and most boxes can hold cube or rectangular prisms not triangular pyrimids or prisms or hexagonal prisms.
What are the 6 shapes which are prisms?
The six common shapes that are classified as prisms include rectangular prisms, triangular prisms, pentagonal prisms, hexagonal prisms, octagonal prisms, and rhombic prisms. A prism is characterized by having two parallel, congruent bases connected by rectangular lateral faces. Each type of prism is named after the shape of its base.
How many different types of prism are there?
There are several types of prisms, classified primarily by the shape of their bases. The most common types include triangular prisms, rectangular prisms, pentagonal prisms, and hexagonal prisms, among others. Additionally, prisms can be categorized as right prisms, where the sides are perpendicular to the base, and oblique prisms, where the sides are slanted. Overall, the variety of prisms is extensive, depending on the number of sides and the angles between them.
What are some prisms?
Prisms are objects that divide the colours of the rainbow. Some prisms are Triangular, Rectangular and etc.
Are polyhedra prisms?
NO, but prisms are polyhedra. Polyhedra include a lot more shapes than just prisms.
How are rectangular prisms are alike?
They are all rectangular prisms!
