Units such as light years and astronomical units are useful because they can be used to measure very large distances without yielding extremely large numbers.

What is the color of light that is the least useful to plans during photosynthesis?
red and blue light is most useful. But others are not.
Do you measure distances to galaxies in light years or astronomical units?
Galaxies are always calculated in light years or parsecs. Most galaxies are calculated in mly of kpc (Million light years or thousand parsecs) because of the distances.The Andromeda Galaxy is our closest large galaxy, and that is 2.54 mly or 778 kpc.If we used AU that would equate to 160,000,000,000 or 160 billion AU.
Which equipment is most useful when measuring two enviromental changes?
A thermometer and light meter are the most useful when measuring two environmental changes.
What units are used to measure distances in the solar system?
well we use three main ones : Light years, parsecs and kilometers, but we usually only use kilometers for our inner solar system __________________ There is also the Astronomical Unit, AU, which is the average distance between the earth and the sun. A parsec is roughly 3.3 light years, and a light year is the distance covered by light in a vacuum in one earth year. um also the distance requires the sun. Since astronomers did not know where to start, they measured everything in the universe starting with the sun.
What unit of metric measurement is most useful for light microscopy?
micrometer
Why is the sundial most useful in the summer?
because there is more sun light
Which equipment is most useful when measurin Barometer and voltmeter Light meter and barometer Voltmeter and thermometer Thermometer and light meter the two environmental changes mentioned above?
A thermometer and light meter are the most useful when measuring two environmental changes.
What two wavelengths of light are least and most useful to photosynthesis?
Red light and blue light.Photosynthesis is not efficient under green light.
What is the most useful unit foe measuring distances within the solar system?
Probably AUs or Astronomical Units. 1AU= 93 million miles or about 150 million km. 1AU is the distance from the Earth to the Sun.
What scale is most useful for measuring distance?
The most useful scale for measuring distance depends on the specific context. For very short distances, scales like centimeters or inches are commonly used. For longer distances, scales like meters, kilometers, or miles are more practical. In astronomy or geology, scales like light-years or astronomical units may be used for extreme distances.
Is light meter and barometer the most useful when measuring environmental changes?
There are many tools used in measuring meteorological changes. The most useful tool depends on which factors are measured. A light meter or photometer measures light intensity while a barometer measures atmospheric pressure.
Would the term light year- the distance light travels in a year or 9.5 trillion km- be useful in a model of the solar system?
No, it is too large a unit so that most of the numbers in the model would be extremely small. The earth is only 0.000015 light years away from the sun. Even Neptune, the furthest planet is just 0.0005 light years.
