Which of the following statements best differentiates between the different properties of waves?

a)

Amplitude refers to the number of wave cycles that pass a given point per unit of time, while frequency represents the maximum displacement of a wave from its equilibrium position.

b)

Wavelength measures the distance between two consecutive points on a wave that are in phase, while period indicates the time taken for one complete wave cycle.

c)

Speed is the rate at which a wave travels through a medium, while amplitude represents the energy carried by the wave.

d)

Frequency is the number of oscillations per unit time, while wavelength is the distance between successive crests or troughs of a wave.

Which of the following statements best identifies the differences between a convex and concave mirror?

a)

A convex mirror bulges inward, causing light rays to converge, while a concave mirror bulges outward, causing light rays to diverge.

b)

A convex mirror bulges outward, causing light rays to diverge, while a concave mirror curves inward, causing light rays to converge.

c)

Both convex and concave mirrors bulge outward, causing light rays to diverge.

d)

Both convex and concave mirrors bulge inward, causing light rays to converge.

Which of the following statements best describes the analysis of the motion of an object in terms of its position, velocity, and acceleration?

a)

Position describes where the object is located, velocity describes how fast the object is moving, and acceleration describes the change in direction of the object.

b)

Position describes the speed of the object, velocity describes the distance traveled by the object, and acceleration describes the rate at which the object changes its position.

c)

Position describes the rate of change of velocity, velocity describes the change in position of the object, and acceleration describes the distance covered by the object in a unit time.

d)

Position describes the change in velocity of the object, velocity describes the rate of change of position, and acceleration describes the location of the object in space.
