What is indirect measurement and how is it useful?

Answer 1

Indirect measurements are useful when it is not possible to measure the object for some reason. Scientists use indirect measurements when the measure the temperature of a flame my measuring the wavelength of the light being given off and calculating the temperature from a formula using that wavelength. The energy of electrons in atoms can only be measured using indirect means.

Answer 2

Indirect measurement is a method of measuring objects or quantities that are not directly accessible or easily measured. It is useful when direct measurement is impractical or impossible, such as in situations where physical contact is not possible. Indirect measurement involves using other known measurements or properties to estimate the desired quantity.

Answer 3

When instead of measuring the specific thing directly you measure some other aspect of the event and from that figure out the actual value. Ex. Lets say that you need to find out the height of a tower, but that you can not measure it from top to bottom with a measuring tape. You can measure the shadow on the ground and with knowledge of the suns position and the angle of the shadow calculate the height of the tower.

Answer 4

Indirect measurement is a technique that uses proportions to find a measurement when direct measurement is not possible.

or taking a small piece of the whole finding the volume or mass of the piece and if you know the mass or volume of the whole you divide the whole m/v by the piece m/v. and dont for get if you have a container of some thing then find the m/v of the empty container and subtract it from the whole m/v before dividing.
