Question
In procedure 2: suppose ?1 = 29.9o and ?2 = 19.2o.
SetUp Carefully align the half round lens to the semicircular area on the protractor. Again, it is important to align it precisely! Look at the diagram to the right carefully. The beam hits the round part of the lens, and enters along the radius of the circle, so it is perpendicular to the surface- along the normal-and does not refract! The beam hits the flat edge of the lens at the same angle as it enters, and then refracts due to the difference in n between the lens and the air.Explanation / Answer
This experiment is to analyze the refraction principle
Here the apparatus is one protracter, glass and one laser beam. The protracter is given to analyze the variation in angle. The laser light is passed over the lens and the variation and there is a change in their angle. This change in angle can be understood by using protracter.
The laser light is passing through two medium. One is air and the other is glass. Both of them have 2 different refractive index. Since they have different refrative index the angle of the laser light will be bit deviate show the angle f refracion in between the two medium.
