What makes shadows?
Shadows are caused when an object blocks part of a beam of light that is falling on a surface. The surface areas receiving less light are darker (less illuminated by the light) and may assume the same general shape of the object causing the shadow.
At what light intensity do you expect there to be no net productivity?
100% light intensity ?
Can an object cause more than 1 shadow?
Yes, if multiple light sources are shining on it, then there will be multiple shadows.
What is a light intensity knob?
The light intensity knob is found on light microscopes and allows you to change the intensity of the light on the sample. Different light intensities allow you to view different parts more clearly.
Si unit for light intensity?
Light intensity is also known as luminosity. Candela is the si unit
Are shadows different colers?
Shadows are typically darker versions of the color of the object casting the shadow. The color of a shadow can be influenced by various factors such as the color and intensity of the light source, the surface reflecting the light, and any other objects nearby affecting the light.
How do you make shadows darker?
Become larger or thicker to block more light.
How does lighting help make an optical illusion?
By creating shadows and altering light intensity.
What happens to the illuminance when you move away from the light source?
The intensity decreases.
What effects the size and tone of shadows formed?
The angle between the light source and the object that light's being shone at, the distance between the light source and object, the amount of light in the environment and the diffraction of the lights, and where the less or more phases of light reach, which cause the shadow to be darker or greyer.
What do shadows look like after sunset?
After sunset, shadows appear longer and darker as the light source moves lower in the sky. The angle of the light creates elongated shadows with more defined edges, adding a sense of depth and contrast to the surrounding environment.
How do you make shadows sharper?
To make shadows sharper, you can increase the light source’s intensity, focus the light on a smaller area, or decrease the distance between the object and the surface where the shadow is cast. Using a direct, strong light source positioned closer to the object will also help create sharper shadows.
What makes shadows?

Why does the limb of the Sun appears darker than the center?
When you face the flashlight towards you, you get the full intensity of the light while when you face it away from you you get some light but not all.
What happens if you continue to increase the intensity of light that plants receives?
If the plant has enough chloroplast to accept the light intensity, it'll continue to grow strong accordingly. It'll develop stronger leaves, stem, and darker in green color foliages. It'll reach a peak where light saturation occur when the plant no longer can grow any stronger even with higher light intensity. Increasing the light intensity further could hurt the plant.
How does the earth's rotation create shadows?
Rotation as such doesn't cause shadows. What causes shadows is when there's something blocking the way between a Surface and a light source.
What is the light intensity in the arctic?
The light intensity is poop!
