A student has to trace the path of way of light through a glass prism. List four precautions he should observe for better results.

In an experiment to trace the path of a ray of light through a triangular glass prism, a student would observe that the emergent ray

A student traces the path of a ray of light through a triangular glass prism for different values of angles of incidence. On analysing the ray diagrams, which one of the conclusions is he likely to draw ?

A student traces the path of a ray of light passing through a rectangular glass. Slab. For measuring the angle of incidence, he must position the protractor in the manner shown in figure :

The path of light rays passing through a glass prism is BEST represented by ________

A teacher asked four students to record the observations of the experiment on tracing the path of a ray of light through a rectangular glass slab. The students recorded their observations under the following headings : (1) Angle of incidence, Angle of refraction, Angle of reflection (2) Angle of incidence, Angle of deviation, Angle of emergence (3) Angle of incidence, Angle of reflection, Angle of emergence (4) Angle of incidence, Angle of refraction, Angle of emergence The correct observations were recorded by the student :

In an experiment to trace the path of a ray of light passing through a rectangular glass slab, four students tabulated their observations as given below. Which student is correct.

In an experiment to trace the path of a ray of light passing through a rectangular glass slab, four students measured the angles of incidence (i), angles of refraction (r) and angles of emergence (e) as shown in the diagrams : The correct measurement is given in the diagram :
