Waves. Basic Physics II

Sound waves are ...

• Fluid waves

• Electromagnetic waves

• Both: mechanical and electromagnetic waves

• None

Types of waves

• Mechanical and Electromagnetic

• Kinetic and potential

• Kinematics and Dynamics

A traveling wave that causes the elements of the disturbed medium to move parallel to the direction of propagation

• Transverse wave

• Longitudinal wave

• Complex wave

• None

The maximum displacement of an element from its normal position

• Crest of the wave

When a wave or pulse travels from medium A to medium B and v_A > v_B, it is inverted upon reflection

• B is equally denser than A

• B is denser than A

• A is denser than B

• None

When a part of the energy in the incident pulse is reflected and part passes, the phenomena is called ...

• Reflection

• Refraction

• Transmission

• Doppler Effect

The speed of the wave does not depend on the properties of the medium

• True

• False

In general, the speed of sound is slower in

• Gases

• Liquids

• Solids

• Equal in all of them

The sound level is measured in ...

• Watt (W)

• Decibels (dB)

• Degree Celsius (°C)

• Watt per meter squared (W/m2)

It is the apparent change in frequency (or wavelength) that occurs because of motion of the source or observer of a wave

• Waves fronts

• Transmission

• Frequency Effect

• None
