Answer 2

(a) The child displayed empathy, kindness, and quick thinking in trying to help the injured motorcyclist.

(b) The car driver displayed a lack of moral values by choosing to ignore the injured person and driving away without providing any assistance.

(c) The phenomenon involved in the observation of beautiful colours in a thin film of oil on water and the splitting of light into different colours by a prism is called interference.

• Interference occurs when two waves of light, in this case, reflected light waves, meet each other and interact constructively or destructively. When the waves interact constructively, they reinforce each other, resulting in bright colours, while when they interact destructively, they cancel each other out, resulting in dark regions.

(d) The appearance of soap bubbles as coloured when seen in sunlight and the splitting of light into seven colours by a prism both follow the phenomenon of interference.

• In the case of soap bubbles, the light waves reflecting off the front and back of the thin film of soap bubble interfere with each other constructively or destructively, resulting in bright colours.
• In the case of a prism, white light is split into different colours due to the different angles of refraction experienced by each colour of light, resulting in a rainbow of colours.
