You can see the desk because it reflects light that falls on it from other sources such as overhead lights, windows, or ambient light in the room. The surface of the desk interacts with this light, absorbing some wavelengths and reflecting others, which allows your eyes to perceive the desk's color and shape.
To see a shadow, you need a source of light, an object to cast the shadow, and a surface for the shadow to be projected onto. When the light is blocked by the object, a shadow is created on the surface opposite the light source.

Yes, humans are able to see light. Our eyes contain cells called photoreceptors that are sensitive to light. When light enters the eye, it is detected by these cells and converted into electrical signals that are sent to the brain for processing, allowing us to see.
A spectroscope works by dispersing light into its component colors using a prism or diffraction grating. Each color corresponds to a different wavelength of light, allowing us to see the distinct colors present in the light source. This phenomenon is known as spectral dispersion.
We are able to see objects around us due to the light that is reflected off of those objects and enters our eyes. This light stimulates the cells in our retina, which then send signals to our brain for processing, allowing us to interpret and perceive the objects in our environment.
we are able to see light source because the light from the light source enters our eyes
Without the light source, you wouldn't be able to see your sample very well!
You need a light source for you to see a object. Without a light source, you wont be able to see anything at all. For example, it is a sunny day and you are sitting underneath a tree in a park reading a book. For you to be able to see your book, there has to be a light source. The only source of light that has the biggest possibility is the sun. The light from the sun travels in a straight line to the book you are reading which then reflects in a straight line into your eyes. The same concept is applied even if you are indoors but instead the light source can be the light bulb or maybe even the light from the sun coming in through the windows. It depends, but a light source is needed for you to be able to see anything.
Humans are able to see objects that are not light sources because they reflect light that is emitted by a light source, such as the sun or a lamp. This reflected light enters our eyes and is processed by the brain to create the perception of those objects in our visual field.
The uses of a magnifier desk lamp are to able to see very small writing/print and be able to read this in a much better light. This can be used for older documents that may have been damaged in the past. Those with eye difficulties would be able to use the lamp for regular reading.
In a cave with zero light, you would not be able to see any reflection from a diamond since there is no light source. However, if there is moonlight, starlight, ambient light from any source, your diamond will sparkle.

When your eyes can detect images, light from a light source(s) is being reflected from the objects you see directly to your retina. For example, you are in a closed room with one overhead light fixture. The light from the light bulb is being filtered and scattered to light up some surfaces in the room. Light travels in a straight line. The shadow below a desk is where there is no direct light (no direct path to the light source). However, light scattered off the wall or chair will still reach below the desk, where you can still see a faded image. When you can see an image, bright or faded, it means that some light has reflected off that surface to reach your eyes. A bright image is seen when more light reaches that surface and reflects to your eyes than a fuzzy image. =========================
No. In order to see a rainbow in front of you, there must be a source of light behind you, and the rainbow you see will only have the colors of the source in it.
Yes u can see the red apple b/c red is the first form of visible light
We cannot see a light source even if 1 opaque material is blocking the light source. Opaque materials do not allow light to pass through them so we cannot see light through them but we can still see light reflected by them.
A light source is a form of energy produced by heat.
