- 1Which model places the Sun at the centre of the solar system?Heliocentric
- 2Who proposed the heliocentric model?Copernicus
- 3What did Galileo discover and what theory did it support?Jupiter's moons,
Heliocentric model - 4What two types of waves do non luminous objects emit?Microwaves and radio waves
- 5What invention allowed the discovery of Uranus, Neptune and Pluto?Telescope
- 6What does the eyepiece of a telescope do?Magnifies the image
- 7What is another name for a converging lens?Convex
- 8Define focal lengthThe distance between the focus and the lens
- 9What happens to waves at boundaries between different materials?Refracted
- 10What two things happen to a wave when it meets a boundary between different materials?change of speed and direction
- 11What can you do to a real image?Project it on a screen
- 12State two factors that affect the magnification of a converging lens.How curved the surface is and how close together the lenses are
- 13What does a reflecting telescope have that a refracting telescope does not?Mirror
- 14How can you change about the primary mirror to make the image brighter?Make the mirror larger
- 15What do waves transfer?Energy
- 16Define frequency.The number of waves passing a point per second
- 17Define wavelengthThe distance from one peak to another peak or one trough to another trough.
- 18Define amplitudeThe maximum distance of a point on a wave from its resting position.
- 19What type of wave are electromagnetic waves?Transverse
- 20What type of wave are sound waves?Longitudinal
- 21What type of waves can be both longitudinal and transverse?Seismic
- 22If a wave carries a surfer 52m in 8 seconds, what is the wave speed? Show your working.52m divided by 8s
equals 6.5m/s - 23If a wave has a wavelength of 13m and has a frequency of 0.5Hz, what is its speed? Show your working.13m multiplied by 0.5Hz
equals 6.5m/s
