### Which of the following statements are true? 14

A system that undergoes periodic motion always has a stable equilibrium position.

### Which of the following statements are true? 14

Simple harmonic motion is periodic motion under the action of a restoring force that is directly proportional to the displacement from equilibrium.

### mass is attached to a vertical spring. The mass exhibits simple harmonic motion between points A and B. Which of the following statements are true? 14

The mass is located at either point A or B when its kinetic energy is at minimum.

### mass is attached to a vertical spring. The mass exhibits simple harmonic motion between points A and B. Which of the following statements are true? 14

The mass is located midway between points A and B when its kinetic energy is at maximum.

### Starting from rest, a solid sphere rolls without slipping down an incline plane. At the bottom of the incline, what does the angular velocity of the sphere depend upon? 9

The angular velocity depends upon the radius of the sphere.

### Starting from rest, a solid sphere rolls without slipping down an incline plane. At the bottom of the incline, what does the angular velocity of the sphere depend upon? 9

The angular velocity depends upon the height of the incline.

### Which of the following statements are true? 16

The pitch of a sound is determined by its frequency.

### Which of the following statements are true? 16

The loudness of a sound is related it its amplitude.

### 33 Which of the following statements are true concerning the reflection of light?

The reflection of light from a smooth surface is called specular reflection.

### 33 Which of the following statements are true concerning the reflection of light?

The reflection of light from a rough surface is called diffuse reflection.

### 33 A ray of light crosses a boundary between two transparent materials. The medium the ray enters has a larger optical density. Which of the following statements are true?

The wavelength of the light decreases as it enters into the medium with the greater optical density.

### 33 A ray of light crosses a boundary between two transparent materials. The medium the ray enters has a larger optical density. Which of the following statements are true?

The frequency of the light remains constant as it transitions between materials.

### 33 A ray of light passes from air into a block of clear plastic. How does the angle of incidence in the air compare to the angle of refraction in the plastic?

The angle of incidence is greater than the angle of refraction.

na > nb

### 33 Suppose a ray of light traveling in a material with an index of refraction na reaches an interface with a material having an index of refraction nb. Which of the following statements must be true for total internal reflection to occur?

The angle of incidence must be greater than the critical angle.

### 36 Consider two diffraction gratings with the same slit separation. The only difference between the two gratings is that one grating has 5 slits and the other 10 slits. Both gratings are illuminated with a beam of the same monochromatic light. Which of the following statements are true?

The grating with 10 slits produces better-defined (narrower) peaks.

### 36 Consider two diffraction gratings with the same slit separation. The only difference between the two gratings is that one grating has 5 slits and the other 10 slits. Both gratings are illuminated with a beam of the same monochromatic light. Which of the following statements are true?

Both gratings produce the same separation between peaks.

### 34 Which of the following statements are true for images formed by thin lenses?

A diverging lens always produces an upright image of an object placed in front of it.

### 34 Which of the following statements are true for images formed by thin lenses?

A diverging lens always produces a virtual image of an object placed in front of it.

### 34 Which of the following statements are true concerning the eye?

Astigmatism refers to a defect in which the surface of the cornea is not spherical. Instead, it is more sharply curved in one plane than another.

### 34 Which of the following statements are true concerning the eye?

The far point of the normal eye is infinity.

### 34 Which of the following statements are true concerning the eye?

Nearsightedness can be corrected with a diverging lens.

### 34 Which of the following statements are true concerning compound microscopes?

In a compound microscope, the final image is a virtual image.
