The diagram shows two narrow beams of light, P and then Q, passing through the same prism. Beams P and Q are both incident on the same point on the prism and at the same angle. Which row correctly compares beams P and Q?| dispersion | nature of light | |
|---|---|---|
| A | only Q is dispersed | P is monochromatic and Q is white light |
| B | only Q is dispersed | P is white light and Q is monochromatic |
| C | only P is dispersed | P is monochromatic and Q is white light |
| D | only P is dispersed | P is white light and Q is monochromatic |
