Ch 13 Physics Part 2

What does line density refer to in the context of sound pulses?

• The frequency of sound waves

• The spacing between sound pulses

• The amplitude of sound waves

• The speed of sound

What happens when line density is high?

• The number of pulses per image decreases

• The frame rate and temporal resolution increase

• The number of pulses per image increases

• The sound quality improves

How does high line density affect frame rate and temporal resolution?

• Both increase

• Both decrease

• Frame rate increases, temporal resolution decreases

• Frame rate decreases, temporal resolution increases

What is the effect of high line density on spatial resolution?

• It degrades spatial resolution.

• It improves spatial resolution.

• It has no effect on spatial resolution.

• It only affects temporal resolution.

How does high line density affect temporal resolution?

• It improves temporal resolution.

• It has no effect on temporal resolution.

• It degrades temporal resolution.

• It enhances both spatial and temporal resolution.

What happens to the frame rate when line density is low?

• The frame rate decreases.

• The frame rate remains the same.

• The frame rate increases.

• The frame rate becomes zero.

What is a characteristic of low line density?

• Tightly packed lines

• More pulses per frame

• Widely spaced lines

• Excellent spatial resolution

Which of the following is true for high line density?

• Higher frame rate

• Poor spatial resolution

• Low temporal resolution

• Fewer pulses per frame

What is the effect of high line density on spatial resolution?

• Poor spatial resolution

• Excellent spatial resolution

• No effect

• Decreased spatial resolution

How does low line density affect temporal resolution?

• Low temporal resolution

• High temporal resolution

• No change

• Decreased temporal resolution
