a student has to perform an experiment on tracing the path of a ray of light passing thru a rectangular glass slab for three different angles of incidence , four of his friends suggest the following options to him:
a) draw the incident rays corresponding to 20 degree , 50 degree, 70 degree as the angles of incidence and fix the 2 points on the incident rays nearly 2 cm apart.
b)draw the ncident rays corresponding to 20 degree,45 degree,70 degree as the angles of incidence and fix the 2 pins on the incident ray nearly 8 cm apart
c) draw the incident rays corresponding to 30 degree, 45 dgree, 60 degree as the angles of incidence and fix the 2 pins on the incident ray nearly 8 cm apart
d)draw the incident rays corresponding to30 dgree,45degree,60 degree as the angles of incidence and fix the 2 pins on the incident ray nearly 2 cm apart.
