Wave Interactions

When a wave hits a fixed end, it is

• Reflected on the same side

• Inverted

When a wave hits a free end, it is

• Reflected on the same side

• Inverted

When two pulses meet up, they bounce off each other

• True

• False

Destructive interference is when two waves interact to produce

• A resultant wave with a greater amplitude

• A resultant wave with a smaller amplitude

Interference of waves involves...

• combination of light and dark bands on a screen

• polarisation of sound or light waves

• diffraction of waves of the same frequency

• superposition of two or more waves

What type of inference is this picture showing

• Constructive

• Destructive

These waves display

• Reflection

• Complete destructive interference

• Constructive interference

If two overlapping waves are in-phase, the resultant wave will have ______ compared to the two waves.

• Greater amplitude
• Greater frequency
• Greater wavelength
• Greater wave speed
