Fig. 22.1 shows a ray of red light from a laser entering a rectangular glass block from the air. Fig. 22.1 When the red light enters the glass block from the air it will refract. (a) Draw the path of the refracted ray inside the glass block in Fig. 22.1. [1] (b) Explain why red l…

(a) Atoms can emit or absorb electromagnetic radiation when electrons move between energy levels. The diagram shows electron transitions $ \Upsilon $ and $ \Xi $ between energy levels in an atom. (i) Draw an arrow on the diagram showing the transition of an electron in the lowest…

This question is about infra red (IR) and ultra violet (UV) radiation. (b) Look at the information about some UV radiation: • The wavelength of the UV radiation is 0.18μm. • The wave speed of the UV radiation is $ 3.0 \times 10^{8} $ m. Calculate the frequency of the UV radiation…
