What else can I help you with?
How can you measure how much light is absorbed by an opaque object?
You can measure the amount of light absorbed by an opaque object using a spectrophotometer, which measures the amount of light that passes through and is absorbed by the object at different wavelengths. The absorbance value obtained from the spectrophotometer can quantitatively indicate how much light is being absorbed by the object.
What makes an object transparent translucent or opaque?
The transparency, translucency, or opacity of an object depends on how much light it allows to pass through. Transparent objects allow almost all light to pass through, translucent objects allow some light to pass through but diffuses it, and opaque objects do not allow light to pass through at all. This is determined by the material's molecular structure and composition.
When light hits an object most of the light is absorbed by what?
When light hits an object, most of the light is absorbed by the surface of the object. The absorbed light energy is then converted into heat, which can lead to the object warming up. The color of the object determines how much of the light is absorbed and how much is reflected.
What an object's index of refraction indicates?
An object's index of refraction indicates how much the speed of light is reduced when passing through that material compared to its speed in a vacuum. It is a measure of the material's optical density and determines how light waves are bent or refracted as they pass through the material. Different materials have different refractive indices, affecting how they interact with light.
Do transparent obects reflect or absorb light?
Transparent objects allow light to pass through them, so they generally do not reflect or absorb much light. Some light may be reflected or absorbed depending on the material and surface properties of the transparent object.

The absorbance value obtained from the spectrophotometer can quantitatively indicate how much light is being absorbed by the object.
What happens when light hits an object it cannot pass through?
If the light can not pass through a object it is opaque . The light will reflect or be absorbed by the object.
What are shadows for?
shadows are actually a black shade of an object. you might don't understand it but let me say it much more clearly. shadows are formed by the light hitting the object and the object then blocks the light so when the light can't get through it forms a shadow.
What three things determine how much light is refracted as it passes through a substance?
medium, reflection, and how dense the object is
Do coloured objects form coloured shadows?
Shadows are simply an area that does not get as much light as the areas around it. That being said, if the object is totally opaque (or you can't see through it), then the shadow will simply be darker (usually a shade of black) because of the lack of light. If the object is transparent, on the other hand, then what light does go through will tint the light that does find it's way through the object.
What makes an object transparent translucent or opaque?
The transparency, translucency, or opacity of an object depends on how much light it allows to pass through. Transparent objects allow almost all light to pass through, translucent objects allow some light to pass through but diffuses it, and opaque objects do not allow light to pass through at all. This is determined by the material's molecular structure and composition.
What happen when light reflects?
When light reflects, on an object it bounces off of the object and you can see the object much more clearly.
When light hits an object most of the light is absorbed by what?
When light hits an object, most of the light is absorbed by the surface of the object. The absorbed light energy is then converted into heat, which can lead to the object warming up. The color of the object determines how much of the light is absorbed and how much is reflected.
Is a shadow formed by light trying to through a solid object?
A shadow is formed when the light can not pass through the object, so a patch of darkness is left behind the object where not much light can reach.This is because the light is either absorbed or reflected by the object.However, some light often still reaches shadowed areas because light is reflected off of other objects nearby, onto the shadow. This is why shadows are not always 100% darkness.
What colour would a red object look through a blue filter?
A red object would appear dark or black when viewed through a blue filter because blue filters absorb red light, preventing it from passing through. This would result in the red object appearing much darker since it is not reflecting or transmitting the blue light that the filter allows to pass.
How much can light microscope magnify an object?
40x
