Energy in the form of electromagnetic radiation. Most often associated with a wavelength that is visible to the eye.?
light energy
What is wavelength nm?
Wavelength is the distance between repeating units of a propagating wave of a given frequency. For light waves, this value is often given in nanometers, abbreviated as "nm". A nanometer is 0.000000001 meters.
What are the equations for wavelength and frequency of light?
The speed of light is fixed and so the wavelength and the frequency of light are related like this:wavelength * frequency = speed of lightYou just have to be careful your units match up. Often wavelengths of light are listed in nanometers, or nm, while the speed of light is often given in meters per second, or m/s. Make sure everything is in terms of meters or your answer will be way off. Frequency is almost always given in terms of 1/seconds, which is also called a Hertz. See the Web Links for more information about the electromagnetic spectrum.
Why do we measure the movement of stars?
Parallax is the apparent change in position of an object when you look at it from different angles. Astronomers often us parallax to measure distances to nearby stars. This method can be used to determine stars' distances up to 400 light-years from Earth.
Why are there few blue colored plants?
Plants absorb blue light well.
What is the unit that astronomers most often use to express the wavelength of light is called?
For visible light, the nanometer (nm) is usually used. For other wavelengths of EM waves, other prefixes can be used with the meter; for example meter, kilometer, millimeter, femtometer, etc.
What is the unit astronomers most often use to express the wavelength of light called?
The wavelength of light is expressed in different metric subunits derived from meters. For example, radio waves are measured in meters, visible light is measured in nanometers, and gamma rays are measured in picometers.I believe that would be the nanometer. In the past, the angstrom (= 1/10 nm) has been frequently used.
Astronomers often locate telescopes on mountains to?
To - minimise the distortion of the received image due to light pollution.
What does a spectrometer measure?
A spectrometer measures properties of light of a specific part of the wavelength. It is often used to measure the intensity of a light.
What is the Dimension of Wavelength?
The give-away should be the word "length" which is hidden in the word "wavelength". Wavelength has the dimensions of length, and is most often stated in meters or centimeters (radio), nanometers (light), etc.

Define light year and explain its value in astronomy?
A light-year is the distance light travels in a year - equivalent to almos 10 million million (or 1013) kilometers. In popular astronomy, distances to stars or galaxies are often stated in light-years; although astronomers often prefer another measure, the parsec, equivalent to about 3.26 light-years.A light-year is the distance light travels in a year - equivalent to almos 10 million million (or 1013) kilometers.

What does a laser wavelength do?
Light wavelengths are indicators of how often photons rise and fall. Visible light, for example, has a wavlength of about 380 nanometres. Laser wavelengths are measured in the same way.
What is the collective noun in astronomers often develop their ideas in a team?
The collective noun is team; a team of astronomers.
What do astronomers use to measure distance to stars?
If you refer to the units, both the light-year and the parsec are often used. A light-year is the distance light travels in a year; about 9.5 x 1012 kilometers (9.5 million million kilometers). A parsec is about 3.26 light-years.
