The ray of light travels slowly in a glass when compared to air thereby light undergoes refraction.
Important Questions on Light
Four students reported the following observation tables for the experiment to trace the path of a ray of light passing through a glass slab for different angles of incidence. The observation likely to be correct are those of student.
While tracing the path of ray of light passing from air through a rectangular glass slab, the setup, in which the best result will be obtained is
The path of a ray of light coming from air passing through a rectangular slab traced by four students are shown by figures P, Q, R and S. Which one of them is correct?
The path of a ray of light coming from air passing through a rectangular glass slab traced by four students are shown as A, B, C and D in figure. Which one of them is correct?
Beams of light are incident through the holes A and B and emerge out of box through the holes C and D respectively as shown in figure. Which of the following could be inside the box?
While performing the experiment on tracing the path of a ray of light passing through a glass slab as shown in the figure, four students interpreted the results as given. Choose the correct option.
A student does the experiment on tracing the path of a ray of light passing through a rectangular glass slab for different angles of incidence. He can get a correct measure of the angles of incidence and angles of emergence by following the label indicated in figure.
A student very cautiously traces the path of a ray through a glass slab for different values of the angle of incidence (). He then measures the corresponding values of the angle of refraction () and the angle of emergence () for every value of the angle of incidence. On analysing these measurements of angles, his conclusion would be:
A student performs the experiment on tracing the path of ray of light passing through a rectangular glass slab for different angles of incidence. He measures the angle of incidence , angle refraction and angle of emergence for all his observations. He would find that in all cases.
AB is the incident ray on a glass slab.
The emergent ray is:
