Physics: General Wave Properties

What is related to amplitude?

• height in wave

• frequency of wave

• energy of wave

• wavelength of wave

A wave is a (a)   energy is transferred through vibrations.

What do waves move?

• particles

• curves

• matter

• energy

Choose the two laws of reflection.

• angle i = angle r

• sin i = sin r

• occurs on smooth surface

• normal, incident and reflected ray on same plane

• sine waves

• transverse waves

• longitudinal waves

• cos waves

• True

• False

Which one of the following is not a feature of wavefronts?

• joins all identical points on a wave

• wavefronts can show wavelength, frequency and speed

• wave motion is perpendicular to the wavefront

• distance between succesive wavefronts is one wavelength

What does not change during refraction?

• Frequency

• Speed

• Wavelength

When light waves are refracted into deep to shallow water, what happens to the wave speed and the wavelength?

• wavelength increases

• wavelength decreases

• wave speed increases

• wave speed decreases

What is not a source of waves?

• Vibrating motion

• Oscillating motion
