### A mass attached to a spring vibrates back and forth. At maximum displacement, the spring force and the

acceleration reach a maximum

### A simple pendulum swings in simple harmonic motion. At maximum displacement,

the acceleration reaches a maximum

### A mass attached to a spring vibrates back and forth. At the equilibrium position, the

velocity reaches a maximum

### A mass-spring system can oscillate with simple harmonic motion because a compressed or stretched spring has which kind of energy ?

elastic potential

amplitude

amplitude

14

all waves

### If you are on a train, how will the pitch of the train's whistle sound to you as the train moves?

the pitch will not change

### The property of sound called intensity is proportional to the rate at which energy flows through

an area perpendicular to the direction of propagation

one-ninth

power

by 20 units

decibels

70dB

### A sound twice the intensity of the faintest audible sound is not perceived as twice as loud because the sound of loudness in human hearing

is approximately logarithmic

resonance

a standing wave

### For a standing wave in an air column in a pipe that is open at both ends, there must be at least

two antinodes and one node

### When an air column vibrates in a pipe that is open at both ends,

all harmonics are present

### When an air column vibrates in a pipe that is closed at one end,

only odd harmonics are present

### In general, sound travels faster through

solids than through gases

### A train moves down the track toward an observer. The sound from the train, as heard by the observer, is__ the sound heard by a passenger on the train

higher in pitch than

refraction

medium

### Which is an example of refraction?

A fish appears closer to the surface of the water than it really is when observed from a riverbank

wavelength

wavelength

### Light is not refracted when it is

striking a wood surface at and angle of 75

### When light passes at an angle to the normal from one material into another material in which its speed is higher,

it is bent away from the normal to the surface

### When light passes at an angle to the normal from one material into another material in which its speed is lower,

it is bent toward the normal to the surface

### When a light ray moves from air into glass, which had a higher index of refraction, its path is

bent toward the normal

### When a light ray passes from water into diamond at an angle of 45, it's path is

bent toward the normal

### The relationship between frequency, wavelength, and speed holds for light waves because

all forms of electromagnetic radiation travel at a single speed in a vacum

### The farther light is from a source

the more spread out light becomes

### If you are reading a book and you move twice as far away from the light source, how does the brightness at the new distance compare with that at the old distance? It is

one-fourth as bright

diffuse, rough

smooth, specular

### When incoming rays of light strike a flat mirror at an angle close to the surface of the mirror, the reflected rays are

close to the mirror's surface

### When a straight line is drawn perpendicular to a flat mirror at the point where an incoming ray strikes the mirror's surface, the angle of incidence and reflection are measured from the normal and

the angles of incidence and reflection are equal

### If a light ray strikes a flat mirror at an angle of 27 from the normal, the reflected ray will be

27 from the normal

### If a light ray strikes a flat mirror at an angle of 14 from the normal, the reflected ray will be

14 from the normal

### If a light ray strikes a flat mirror at an angle of 29 from the normal, the reflected ray will be

29 from the normal

### If a light ray strikes a flat mirror at an angle of 30 from the normal, the reflected ray will be reflected at an angle

60 from the mirror's surface

### In a vacuum, electromagnetic radiation of short wavelengths

travel as fast as radiation of long wavelengths

### When red light is compared with violet light,

both travel at the same speed

### If you know the wavelength of any form of electromagnetic radiation , you can determine its frequency because

all wavelengths travel at the same speed
