What is a wave?

• A disturbance that carries energy through matter or space

• A particle that carries matter through energy or space

• A particle that carries energy through matter or space

• A disturbance that carries matter through energy or space

Which type of wave vibrates perpendicular to the direction of its motion?

• Transverse wave

What is the wavelength of a wave?

• The number of cycles in a given time period

• The length of one cycle of the wave

• The maximum disturbance of the wave from its zero point

What is the principle of superposition in waves?

• The displacement of a medium caused by two or more waves is the algebraic sum of the displacements caused by the individual waves

• The displacement of a medium caused by two or more waves is the multiplication of the displacements caused by the individual waves

• The displacement of a medium caused by two or more waves is the division of the displacements caused by the individual waves

• The displacement of a medium caused by two or more waves is the subtraction of the displacements caused by the individual waves

What is the law of reflection for waves?

• The angle of incidence is opposite to the angle of reflection

• The angle of incidence is less than the angle of reflection

• The angle of incidence is greater than the angle of reflection

• The angle of incidence is equal to the angle of reflection

What happens when two pulses with equal but opposite amplitudes meet?

• Destructive interference

• Constructive interference

• No interference

• Wave cancellation

What is refraction in waves?

• The superposition of waves in the same medium

• The reflection of waves at the boundary of the medium

• The interference of waves in the same medium

• The change in the direction of waves at the boundary between two different media

What determines the speed of a mechanical wave?
