Question

When the white light enters into a glass prism:

Options

• the different wavelengths bend through different angles.

• the different wavelengths bend through same angle.

• in bending through different angles the colours separate.

• the different wavelengths bend through different angles and in bending through different angles the colours separate.

Answer 1

The different wavelengths bend through different angles and in bending through different angles the colours separate.

Explanation:

Different wavelengths bend through different angles in a prism, so the colours separate. They do not all bend through the same angle.
