What else can I help you with?
What part of the microscope is used to adjust the amount of light passing through the observed object?
The diaphragm or iris controls the amount of light passing through the observed object. It can be adjusted to change the brightness and contrast of the specimen.
Which term describes matter that scatters light allowing only a part of the light rays to transmit through?
The term for matter that scatters light and allows only a part of the light rays to transmit through is "translucent." This quality can be seen in materials like frosted glass or wax paper.
What happens to the light rays that are not reflected by and object?
Light rays that are not reflected by an object are either absorbed or transmitted through the object. Absorption occurs when the object's material absorbs some of the light energy, converting it into heat. Transmission happens when the light passes through the object without being reflected or absorbed.
What part of the eye captures the light rays that are reflected off an object being looked at?
The retina is the part of the eye that captures the light rays that are reflected off an object being looked at. It contains specialized cells called photoreceptors that convert light into electrical signals which are then sent to the brain for processing.
Why cant light travel through objects?
There are some objects through which light can travel, others it cannot. Light is a part of the electromagnetic spectrum and each part has a certain energy level. The energy required to travel through an object varies with the make up of that substance. The property an object has for allowing the passage of electromagnetic radiation to pass is called its transparency. An object may not allow light to pass but allow x-rays to pass because x-rays have more energy than light. There fore human flesh, for instance, is opaque to light but transparent to x-rays. There are other things involved but this is a simplified explanation.
What Object allows part of the light pass through?
light fabric will let some light in and a fuzzy plastic cup

Do coloured objects form coloured shadows?
Yes, colored objects can cast colored shadows. When light passes through or bounces off a colored object, it absorbs certain wavelengths of light and reflects others, giving it its color. This colored light then creates a colored shadow when the object blocks part of the light from reaching a surface.
What part of the eye captures light rays that are reflected off the object being looked at?
The eye does not actively capture the light rays that are reflected off the object being looked at. They pass into the eye through the cornea..
Is a traffic light part of the environment?
No. A traffic light is a man made object, not part of the natural environment.
What happens to the light rays that are not reflected by and object?
Light rays that are not reflected by an object are either absorbed or transmitted through the object. Absorption occurs when the object's material absorbs some of the light energy, converting it into heat. Transmission happens when the light passes through the object without being reflected or absorbed.
What happens to light waves when it strikes an object?
light can do one of 4 things. it can, a] bounce off of an object, b] get absorbed, or c] be dispersed. this happens when white light goes through a prism, and comes out as all colors of the visible spectrum, ROYGBIV. [red, orange, yellow, green, blue, indigo, violet] and refract d]
Why in Light refraction do black objects remain black?
Light "refraction" is the bending of light as it passes through a transmitting medium, Refraction has nothing to do with black objects. A black object reflects no parts of the visible part of the spectrum, it absorbs them all. A white object reflects all parts of the visible spectrum. A red object reflects the red part of the spectrum, absorbing the rest.
What part of the eye captures the light rays that are reflected off an object being looked at?
The retina is the part of the eye that captures the light rays that are reflected off an object being looked at. It contains specialized cells called photoreceptors that convert light into electrical signals which are then sent to the brain for processing.
Does the pupil absorb the light?
The pupil is actually the absence of the iris (colored part of the eye), so it only allows light to pass through it and helps control how much light passes to the back of the eye.
