WeyPhys KS3 Waves

What does a wave transfer?

• Charge

• Particles

• Energy

• Electrons

What are the two main types of wave?

• Hello and goodbye

• Water and radio

• Transverse and longitudinal

• Electromagnetic and light

Which of these is a longitudinal wave?

• Sound

• Ripples on a pond

• X-rays

• Ultra-violet

What is the top part of a transverse wave called?

• The amplitude

• The maximum

• The peak

• The frequency

What do you call the distance from one peak to the next?

• The amplitude

• The frequency

• The volume

• The wavelength

The frequency of any wave is the...

• Number of waves that pass a point per minute

• Number of waves that pass a point per hour

• Number of waves that pass a point per day

• Number of waves that pass a point per second

What happens when light waves hit a flat shiny surface?

• They get absorbed

• They are refracted

• They are scattered

• They are reflected

What happens to light rays when they hit an uneven reflective material like a piece of white paper?

• They are reflected

• They get absorbed

• They are refracted

• They are scattered

What do you call it when two travelling waves peaks meet, creating a larger peak?

• Wave addition

• Superposition

• Destructive interference

• Maximisation

What would happen if a peak travelling right, met a trough, with an equal amplitude travelling left?

• The two waves would add to make a peak,double the original size

• Nothing - there would be no effect

• The waves would totally cancel each other out where they crossed over

• The waves would reflect off each other
