ICSE Physics Grade 10-Refraction of Light

Question 1 of 3

1

In refraction of light through a prism, the light ray:

Select one of the following:

  • Suffers refraction only at one face of the prism

  • Emerges out from the prism in a direction parallel to the incident ray

  • Bends at both the surfaces of prism towards its base
