  • Define wavelength
    The distance between two identical points on a wave
  • Name the 7 parts of the Electromagnetic Spectrum
    1. Radiowaves
    2. Microwaves
    3. Infrared radiation
    4. Visible Light
    5. Ultraviolet
    6. XRays
    7. Gamma Rays
  • What is the unit for frequency
    Hz
  • List 1 danger of microwaves
    Cells can be damaged if the water inside them is heated
  • Define "Braking Distance"
    The distance travelled between pressing the brake and the car stopping
  • What happens if you place the LIKE poles of a magnet together (E.g. Red and Red, Blue and Blue)
    They will repel from eachother
  • State 2 ways that magnetic fields can be viewed
    • Using iron fillings
    • Plotting compasses
  • Give an example of a Longitudinal Wave
    Sound waves
  • Give 3 examples of Scalar Quantities
    • Speed
    • Distance
    • Energy
  • List 1 danger of Infrared Radiation
    It can cause skin burns
  • What is the unit for Amplitude
    m
  • Define "Compression"
    The point on a longitudinal wave where the vibrations are closest together
  • What happens to a wire when current flows through it
    A magnetic field is created around the wire
  • What is the unit for wave speed
    m/s
  • Define a "Permanent Magnet"
    A magnet that has its own magnetic field with North and South poles.
  • State the unit for "Work done"
    Joules
  • Define "Trough"
    The bottom of a wave
  • Give 4 examples of Vector Quantities
    • Velocity
    • Displacement
    • Force
    • Momentum
  • Define a "Transverse Wave"
    A wave where oscillations are perpendicular to the direction of energy transfer
  • What is a danger of Visible Light
    Can cause blindness
  • Define a "Period" (this isnt biology lol)
    The time it takes for one full wave to form
  • Define "Frequency"
    The number of waves passing a point per second
  • What is a danger of Gamma Rays
    Causes mutations in cells, leading to cancer
  • Define "Resultant Force"
    A single force that has the same effect as all forces together OR the overall force
  • Define "Peak"
    The top of a wave, also called a crest
  • State the unit for "Force"
    Newtons
  • Define "Rarefaction"
    The point on a longitudinal wave where the vibrations are the furthest apart
  • State Newton's Third Law
    Every action has an equal and opposite reaction
    Example: If you pull on a door, the door pulls on you
  • What is stopping distance made up of
    Thinking Distance + Braking Distance
  • State the unit for "Mass"
    Kilogram
  • What is the unit for "Period"
    s
  • State Newton's First Law
    An object at rest will remain at rest, or a moving object will keep moving at a constant speed UNLESS a resultant force acts upon it
  • Which part of the Electromagnetic Spectrum has the highest frequency
    Gamma Rays
  • What is a longitudinal wave
    A wave where oscillations are parallel to the direction of energy transfer
  • State the unit for weight
    Newtons
  • Define "Amplitude"
    The distance from the peak of a transverse wave to the rest position
  • The closer the lines are in a magnetic field...
    ... the stronger the magnetic field is
  • What is the unit for "Wavelength"
    m
  • What is a danger of "Ultraviolet"
    It causes mutations in skin cells, leading to skin cancer
  • Define "Thinking Distance"
    The distance travelled during the time taken to react after seeing a hazard
