  • Q7
    How are radio waves produced?
    By oscillations in electrical circuits
    If an electron in an atom drops from one energy level to a lower level

  • Q8
    Why do ultraviolet waves have more energy than microwaves?
    The energy depends on the frequency, and ultraviolet is lower frequency than microwaves.
    The energy depends on the frequency, and ultraviolet is higher frequency than microwaves.
    The energy depends on the speed, and ultraviolet travels at higher speed than microwaves.
    The energy depends on the speed, and ultraviolet travels at lower speed than microwaves.

  • Q9
    Why would spying organisations trying to intercept communications prefer people to use the radio signals of their mobile phones, rather than sending computer messages via optical fibres?
    Optical fibres are more secure because the signals stay in the fibre.
    Radio equipment is more expensive than optical fibres.
    Optical fibres are more expensive than radio equipment.
    The light waves in optical fibres have a shorter wavelength than radio waves.

  • Q10
    When experimenting with a cobalt-60 gamma ray source, why should a scientist always use a thick lead shield?
    The lead will reflect gamma rays back into the experiment so they are all usefully used.
    The lead will absorb gamma rays, reducing the exposure to the scientist.
    The gamma rays can be used to identify cracks in the lead.
    The lead will produce additional gamma rays to supplement the weak cobalt-60 source.

  • Q11
    Why are gamma rays useful for sterilizing surgical instruments?
    Gamma rays are ionizing radiation which can kill bacteria.
    Gamma rays are often used to make food last longer by killing disease-carrying organisms.
    Gamma rays are very high frequency and this resonates the bacteria off the instruments.
    Hospitals already have gamma sources as part of the cancer treatments so it saves money.
