Physics Quiz Wave

A biological sonar activity used by animals to locate and identify nearby objects by sending ultrasounds and "hearing" them reflected back from them. *

Standing waves are created by *

• two identical waves reflecting off each other

• two identical waves being diffracted together

• two identical move through each other in opposite directions

• two identical waves diffracted from two different sources

Sound is best transmitted in *

• air

• water

• closed room

• solid hard floor

Sound may still be heard around corners and small openings even when its source is out of sight because of *

• Straight line propagation of wave.

• Diffraction

• Refraction

• Reflection

The change in pitch due to the relative motion of the source and the receiver is known as *

• Doppler effect

• Total internal reflection

• resonance

• reverberation

A sonic boom is heard by a ground bystander. This only means that *

• a loud airplane is approaching

• the plane's muffler must have been lost or dislodged

• a supersonic plane has just passed by

• a subsonic plane is flying above at very low altitude

If a sonic boom is heard after an aeroplane has passed, this only means that *

• the subsonic plane is moving at less than Mach 1.

• the transonic plane is moving at Mach 1 yet is not able to break the sound barrier.

• the supersonic plane is moving at greater than Mach 1 yet still unable to break the sound barrier.

• the supersonic plane has just broken the sound barrier.

During a constructive interference of two incoming wave fronts, which of their properties add up? *

• Amplitude

• speed

• wavelength

• frequency

Waves formed in the atomic level caused by the fast moving light particles similar to orbital electrons *

• transverse wave

• matter waves

• compressional waves

• electromagnetic waves

A characteristic common to sound waves and light waves is that they *

• are longitudinal

• are transverse

• travel in a vacuum

• transfer energy
