What is the strength of light falling on an area called?
The strength of light falling on an area is called illuminance, and it is measured in lux (lx). Lux is a unit of measurement that represents the amount of light that reaches a surface.
Bodies which give out their own light are called?
Bodies that emit their own light are called "luminous" bodies. Examples include stars, such as our Sun, and certain types of bioluminescent organisms. In contrast, "non-luminous" bodies do not produce their own light and can only be seen by reflecting light from other sources.
How we get shadows?
Because something opaque comes between the light source and the surface onto which the light is falling.
What is light measured in?
Light is measured in units called lux (luminous flux per unit area) or lumens (total amount of light emitted by a source). Lux is commonly used to measure the intensity of light falling on a surface, while lumens are used to measure the total output of light from a source.
If cardboard were four times the unit distance away from the bulb how much would the light falling on the cardboard be?
The intensity of light falling on the cardboard would be 1/16th of the original intensity because the intensity of light is inversely proportional to the square of the distance from the source.
What is the strength of light falling on an area called?
The strength of light falling on an area is called illuminance, and it is measured in lux (lx). Lux is a unit of measurement that represents the amount of light that reaches a surface.
Why are meteors called falling stars?
They are called falling stars because the narrow streak of light looks as if a star is falling from the sky.
Light mist of droplets falling to the earth are called?
The light mist of droplets falling to the earth is called "drizzle." Drizzle consists of very small water droplets that appear as a fine mist or light rain.
What is it called when light reflects in all directions?
Scattering. Caused by the light falling on 'bumpy' surfaces.
What is a light shower called?
A light shower is usually called a drizzle. It consists of very fine droplets of water falling slowly from the sky.
What is the path of light coming from a meteoroid called?
It's called a 'meteor', 'shooting star', 'falling star', etc.
What is the littlest drop of rain called?
The smallest drop of rain is called a drizzle. It refers to very light rain falling in fine drops.
What is the glow called under ultraviolet light?
The glow seen under ultraviolet light is called fluorescence. This phenomenon occurs when certain substances absorb ultraviolet light and then emit visible light in response.
Has anyone experienced a light fixture falling out of the ceiling?
Yes, some people have experienced a light fixture falling out of the ceiling.
Narrow lines of colors with no light in between them are called what?
Narrow lines of colors with no light in between them are called dark lines. They are typically seen in the spectrum of light when certain wavelengths are absorbed or blocked.
Why does spectrum of light happen?
White light is a mix of different frequencies; with certain equipment, it is possible to separate it into its components. This separated version is called a "spectrum".White light is a mix of different frequencies; with certain equipment, it is possible to separate it into its components.

What do meteors and meteorites look like?
Meteors look like bright streaks of light in the sky - some people call them "shooting stars" or "falling stars". What you saw was a meteor. The bright streak of colors and light is from the meteoroid burning up in our atmosphere from friction with the air. Most meteoroids are small - maybe the size of a golf ball or even smaller. But they leave a bright streak because they vaporize almost completely in the upper atmosphere. Sometimes, a meteoroid that is a little larger (maybe the size of a grapefruit or a watermelon) actually survives the trip through the atmosphere and lands on the ground - then it is called a meteorite. Meteorites resemble normal rocks except that they may be pitted from the heat of reentry, or smooth and glassy.
