Physics Revision

The energy of heat, related to the motion of particles within a substance is known as:

• Nuclear energy

• Thermal energy

• Fire energy

• Light energy

Which of the following is not a main process of heat transfer:

• Convection

• Radiation

• Transpiration

• Conduction

Which of the following is not an example of a mechanical wave:

• Seismic wave moving through soil

• Light wave travelling from the sun

• Sound wave vibrating off an object

• Water wave travelling through the ocean

The height of a wave is known as the:

• Frequency

• Wavelength

• Amplitude

• Pitch

The wavelength of a wave is best described as:

• The distance between two consecutive crests or troughs

• The energy carried by the wave

• The time it takes for one complete oscillation of a wave

• A transverse wave

Which of the following is an example of a longitudinal wave?

• Radio wave

• Sound wave

• Water wave

• X-ray

If the wavelength of a wave is 10, what is the frequency?

• 0.1 Hertz

• 10 Hertz

• 0.01 Hertz

• 100 Hertz

How does the medium a sound wave travels through influences the speed at which it

travels.

• • Higher temperatures increase particle movement, which helps sound travel faster.

• The medium does not influence sound waves at all

• Sound waves speed up no matter what material they pass through

• 
  Denser materials tend to slow down sound because particles are more tightly packed, making it harder for vibrations to pass through.

For the wave shown in the diagram, find the amplitude and wavelength.

• Amplitude = 10, Wavelength = 10

• Amplitude = 2, Wavelength = 16

• Amplitude = 20, Wavelength = 50

• Amplitude = 1, Wavelength = 5

What is the relationship between wavelength and frequency for the waves of the

electromagnetic spectrum:

• The longer the wavelength the higher the frequency

• The longer the wavelength the lower the frequency

• The shorter the wavelength the lower the frequncy

• There is no relationship
