Oh.... its too simple yrr..... didn't you get any difference between glass slab and glass prism !!!!
if u hav noticed then u definitely knows about their structure or their model.

glass prism produce spectrum or dispersion of light jst becz of their 60 degree angled faces......
bt if we talk abt the glass slab...
then their faces are parllel to each other and jst becz of that galss slab doesnt produce any spectrum through their faces !!!!

hope uh got it !!!

A glass prism is able to produce a spectrum when a white light is pass...
Why does a glass prism produce a spectrum but a glass slab does not?


When white light is passed through a glass prism, it undergoes refraction, which causes it to split into its constituent colors. This is because the refractive index of glass varies with the wavelength of light, with shorter wavelengths being refracted more than longer wavelengths. The result is a spectrum of colors, with violet being refracted the most and red the least.


However, when white light is passed through a glass slab, it does not undergo sufficient refraction to produce a spectrum. This is because a glass slab has parallel sides, which means that the angle of incidence and the angle of refraction are the same for all wavelengths of light. As a result, there is no dispersion, and the light emerges from the slab in the same colors as it entered.


Key differences between a glass prism and a glass slab



  • Shape: A glass prism has a triangular shape, while a glass slab has a rectangular shape with parallel sides.

  • Refraction: A glass prism causes sufficient refraction to split white light into its constituent colors, while a glass slab does not cause enough refraction to produce a spectrum.

  • Angle of incidence and refraction: The angle of incidence and the angle of refraction are different for different wavelengths of light in a glass prism, but they are the same for all wavelengths in a glass slab.



Applications of glass prisms and glass slabs



  • Glass prisms: Glass prisms are used in optics to split light into its constituent colors, to correct chromatic aberration in lenses, and to reflect light in binoculars and other optical instruments.

  • Glass slabs: Glass slabs are used in optical experiments to demonstrate the principles of refraction and reflection, and to measure the refractive index of different materials.

Similar Class 10 Doubts

Read the extract given below and answer the questions that follows:There are many activities that are undertaken by directly using natural resources. When we produce a good by exploiting natural resources, it is an activity of the primary sector. Since most of the natural products we get are from agriculture, dairy, fishing, forestry, this sector is also called agriculture and related sector. The secondary sector covers activities in which natural products are changed into other forms through ways of manufacturing that we associate with industrial activity. It is the next step after primary. The product is not produced by nature but has to be made and therefore some process of manufacturing is essential. After primary and secondary, there is a third category of activities that falls under tertiary sector and is different from the above two. These are activities that help in the development of the primary and secondary sectors. These activities, by themselves, do not produce a good but they are an aid or a support for the production process. The various production activities in the primary, secondary and tertiary sectors produce a very large number of goods and services. Also, the three sectors have a large number of people working in them to produce these goods and services. The value of final goods and services produced in each sector during a particular year provides the total production of the sector for that year. And the sum of production in the three sectors gives what is called the Gross Domestic Product (GDP) of a country. It is the value of all final goods and services produced within a country during a particular year. GDP shows how big the economy is.Q. Which of the following statement is not true?
