Tick two boxes. refracting reflecting converging diverging Which two things is the prism in doing to the light? Tick two boxes. diffracting dispersing focusing refracting Which colour light will be seen at point X, at the bottom edge of the visible spectrum? A sensitive thermometer shows a small rise in temperature when held at point Y, just above the top edge of the visible spectrum. Which type of electromagnetic radiation is the thermometer detecting? Suggest why this radiation is present.

A filament lamp emits white light, which passes through a small hole in a card. The light spreads out from the hole, as shown in . glass lens glass prism card A B Q P filament lamp (white light source) screen The light from the hole then passes through a glass lens and a glass prism, and finally reaches a screen. State what is seen in the region AB on the screen. In , what two things are shown happening to the light at surface PQ? Tick two boxes. diffraction dispersion reflection refraction shows the same arrangement as in , but with the prism removed. glass lens filament lamp (white light source) screen On , continue the rays until they reach the screen. Describe fully what is now seen on the screen.
