Wave Properties Quiz

What kind of waves are electromagnetic waves?

• Longitudinal waves

• Transverse waves

• Mechanical waves

• P-waves

Which of these is not a characteristic of a wave?

• amplitude

• period

• mass

• velocity

What is the relation between a wave’s energy and its amplitude?

• There is no relation between the energy and the amplitude of a wave.

• The energy of a wave increases with an increase in the amplitude of the wave.

• The energy of a wave decreases with an increase in the amplitude of the wave.

What is a wave?

• A wave is particles that spread from a single origin

• A wave is a disturbance that spreads from the place where it was created.

• A wave is matter that provides volume to an object.

• A wave is matter that provides mass to an object.

A wave travels 2m every 2 cycles. What is its wavelength?

• 4m

• 2m

• 0.5m

• 1m

What properties does a loud, high pitched whistle have?

• high amplitude, high frequency

• high amplitude, low frequency

• low amplitude, high frequency

• low amplitude, low frequency

The angle of incidence at a plane mirror is 25°. The angle of reflection is:

• 15

• 25

• 65

• 70

A light ray strikes a mirror as shown in the diagram. Identify the numbered parts.

• 1 = incident ray, 2 = normal, 3 = angle of incidence

• 1 = incident ray, 2 = normal, 3 = angle of reflection

• 1 = reflected ray, 2 = normal, 3 = angle of reflection

• 1 = normal, 2 = incident ray, 3 = reflected ray

Why are diverging mirrors often used for rear-view mirrors in vehicles?

• It gives a wide range of view.

• It gives a focused image.

• It gives a narrow range of view.

• It scatters the image

When light travels from water into air its speed:

• increases

• stays the same

• decreases
