Quiz Answer Key and Fun Facts

1. Which of these is true of X-rays, gamma rays, infra-red, ultra-violet and visible light?

Answer: They all travel with the same speed in a vacuum

They are all electromagnetic waves which travel at the same speed in vacuum.

2. A copper plate is heated to 100 degrees centigrade, and then cools by emitting radiation predominantly of which type?

Answer: infra-red radiation

Hot bodies emit most of their heat radiation in the form of short wavelength infra-red rays.

3. To store gamma radioactive substances, a box should be made of which material?

Answer: lead

Radioactive particles and rays are absorbed by lead.

4. The joule is a derived unit of energy named for the physicist named Joule. What nationality was he?

Answer: English

James Prescott Joule was born in Lancashire in 1818 and carried out research on the relation of heat to energy. This work led to the eventual law of thermodynics by scientists carrying out developments of Joule's pioneering work.

5. Home electricity meters are 'read' so that the cost of the electricity used can be calculated. Which of these does the meter record?

Answer: energy used

Meters record the amount of electrical energy used in kilowatts per hour.

6. The sound made when an aircraft exceeds the speed of sound is called what?

Answer: Sonic boom

The sound is caused by the pressure waves created by the aircraft as it goes faster than the speed of sound.

7. What does the hot metal filament in a cathode ray tube emit?

Answer: Electrons

The metal emits electrons via thermionic emission.

8. The femtometre is also known by which name?

Answer: Fermi

The femtometre is a unit of length. The name of fermi is used in nuclear physics to honour Enrico Fermi, an Italian scientist who was a pioneer in the creation of nuclear reactors.

9. Which of the materials listed absorbs infra-red radiation best?

Answer: dark animal fur

Black surfaces absorb and emit infra-red radiation well.

10. The resistance to change of a moving body in its state of motion is caused by which of these?

Answer: Inertia

All bodies have inertia which is resistance to changes in motion.
