Question

what is spectrum and angle of deviation
​

Answer 1

Answer:

A spectrum is a condition that is not limited to a specific set of values but can vary, without steps, across a continuum. The word was first used scientifically in optics to describe the rainbow of colors in visible light after passing through a prism.

The angle of deviation is the angle between the direction of the refracted ray and the direction of the incident ray when a ray of light passes from one medium to another.

Explanation:

Answer 2

Answer:

a band of colours, as seen in a rainbow, produced by separation of the components of light by their different degrees of refraction according to wavelength.

The angle of deviation is the angle between the direction of the refracted ray and the direction of the incident ray when a ray of light passes from one medium to another
