Light intensity is measured in LUX, which is defined as LUMENS/square meter. Lumens derives from the base unit CANDELA.

The measure of how much a ray of light bends when it enter the material?
The measure of how much a ray of light bends when it enters the material is called the index of refraction.
What is the measure of how much a ray of light that bends when it enters the material?
This is called refraction.
What is a measure of how much heat energy and object has?
pyrometry utilise a electrical device called a pyrometer to measure the amount of heat-- light exuding from a body as a measure of heat/ radiated heat .
What can scientist measure when light rays are emmitted by a moving source?
Scientist measure when light rays are emitted by a moving source the speed of light. Depending on the moving force they can also measure bending light.
What equipment to use to measure wavelength?
Electromagnetic radiation is just light. You can measure light with a light meter, which tells you intensity, or a camera sensitive to different frequencies. You can also use a magnetometer (Gaussmeter) to measure the B field component or a voltmeter to measure the E field component.Your eyes are instrumentstha measure EM radiation between 300 and 700 microns. We call this type of EM radiation "visible light." Other detectors of EM radiation ar CCD chips in digital cameras, and IR detectors in appliances with rerote controls.spectroscope?
What are the units called that measure distances to stars?
They measure them in light-years.
Why is light called elctromagnetic radiation?
because it resides in the electromagnetic spectrum which is the measure of light.
What is the number of centimeters between waves of light?
The measure of a light's frequency is called wavelength.
The measure of how much a ray of light bends when it enter the material?
The measure of how much a ray of light bends when it enters the material is called the index of refraction.
What is distance to stars usually called?
light year the DISTANCE light travels in a year so 'light year' is not a measure of time.
What is the measure of how much a ray of light that bends when it enters the material?
This is called refraction.
What is it called when you measure distance between stars?
usually the space is measured in light years
How does the human eye see color?
The retinas in the eyes have receptors for color called cones(also known as cone cells). You have one that measures the amount red light, another measures green light, and the third measures light intensity.Your occipital lobes in your brain actually process this information as color by deducing the amount of blue light from the other three factors.The Cone cells measure Red light, Green light, or Blue light. Other cells called Rod cells measure intensity. Humans have full tricolor vision, not bicolor.Most other mammals have only bicolor vision: Cone cells measure Yellow light or Blue light. Rod cells measure intensity.Birds have Quadcolor vision: Cone cells measure Red light, Green light, Blue light, or Ultraviolet light. Rod cells measure intensity.
A unit of length used to measure how far light travels in one year is called?
A "Light Year".Roughly 5,878,700,000,000 miles .
What is the unit measure of light?
Candela (cd) is the unit of luminous intensity of a light source in a specific direction. It is also called candle.
Who is the scientist use the light year to measure the speed of light?
It doesn't work that way. The light-year is not used to measure the speed of light. It works the other way round: First, the speed of light is determined through other methods, then the distance called a light-year is calculated based on that measurements.
If you create a wave that is opposite to the light wave can you remove the light?
Absolutely. Devices called interferometers are used to measure small distances in exactly that way.
