Physics Measuring Instruments Questions

Multiple choice

Which instrument is used for measuring the lengths of arbitrary curved lines (such as those in a map)?

  1. Maptometer

  2. Opisometer

  3. Atlasto

  4. Isometer

Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

An opisometer is a specialized measuring instrument with a small wheel that traces curved lines on maps, converting the distance traveled by the wheel into linear measurements. This tool is essential for accurately measuring irregular paths like rivers, roads, or borders that cannot be measured with a straight ruler. The other options are either made-up terms or incorrect instruments for this purpose.

Multiple choice

Which of the following statements is/are false a. The amount of sunshine a place gets depends upon the time of the day and the season. b. An instrument called barometer is used to measure the rainfall of a place. c. Maximum and minimum thermometers are used to record the maximum and minimum temperature everyday.

  1. only a

  2. a and b

  3. only b

  4. a and c

  5. only c
Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation

An instrument called barometer is used to measure the rainfall of a place, is a false statement. The instrument is called a rain gauge. Thus, this is the correct option.

Multiple choice

Atmospheric pressure is measured by

  1. hygrometer

  2. barometer

  3. altimeter

  4. hydrometer
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

A barometer is a scientific instrument used to measure atmospheric pressure. Hygrometers measure humidity, altimeters measure altitude, and hydrometers measure the specific gravity of liquids.

Multiple choice

_____ is used to measure the intensity of earthquake.

  1. Seismograph

  2. Radar

  3. Ammeter

  4. Binocular
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

A seismograph is an instrument used to detect and record the intensity and duration of earthquakes. While the Richter scale measures magnitude, the seismograph is the physical device that captures the seismic waves.

Multiple choice

Which instrument is used to record the sound under the water?

  1. Hydrophone

  2. Perimeter

  3. Rectifier

  4. Gravimeter

Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

A hydrophone is a microphone designed to be used underwater for recording or listening to underwater sounds. The other instruments listed are used for different measurements like pressure or gravity.

Multiple choice

Which is used to measure rainfall?

  1. Lactometer

  2. Hydrometer

  3. Pluviometer

  4. Altimeter
Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation

A pluviometer, also known as a rain gauge, is an instrument used to measure the amount of liquid precipitation over a set period.

Multiple choice
