Waves

Sound waves are described as:

• mechanical and transverse

• mechanical and longitudinal

• electromagnetic and transverse

• electromagnetic and longitudinal

A light wave strikes the Moon and reflects toward

Earth. As the light wave travels from the Moon

toward Earth, the wave carries:

• energy, only

• matter, only

• both energy and matter

• neither energy nor matter

The time required to produce one cycle of a wave is known as the wave's

• Amplitude

• Frequency

• Period

• Wavelength

A beam of monochromatic light of frequency $f=5.09\times10^{14}$   Hz has a wavelength of 589 nanometers in air. What is the wavelength of this beam in Lucite?

• 150 nm

• 393 nm

• 589 nm

• 884 nm

The effect produced when two or more waves pass through the same point simultaneously is called

• Interference

• Diffraction

• Refraction

• Resonance

A student claps his hands once to produce a sudden loud sound that travels through air. This sound is classified as

• longitudinal mechanical wave

• longitudinal electromagnetic wave

• transverse mechanical wave

• transverse electromagnetic wave

A student generates water waves in a pool of

water. In order to increase the energy carried by

the waves, the student should generate waves

with a:

• greater amplitude

• higher frequency

• greater wavelength

• longer period

A wave generator produces straight, parallel

wave fronts in a shallow tank of uniform-depth

water. As the frequency of vibration of the

generator increases, which characteristic of the

wave will always decrease?

• amplitude

• phase

• wavelength

• speed

A space probe produces a radio signal pulse. If

the pulse reaches Earth 12.3 seconds after it is

emitted by the probe, what is the distance from

the probe to Earth?

• 3.71 × 10² m

• 4.10 × 10⁸ m

• 4.07 × 10³ m

• 3.69 × 10⁹ m
