What else can I help you with?
Can you say that shadow is the consequence of rectilinear propagation of light?
Yes, shadows are formed when an object blocks the path of light, resulting in a region of reduced illumination behind the object. This is due to rectilinear propagation of light, where light travels in straight lines until it is blocked or redirected by an object, creating shadows.
Which property of light is illustrated by the fact that we cannot see around a corner?
The fact that we cannot see around a corner is due to the property of light called "line of sight." Light travels in straight lines, and when an object blocks our direct line of sight, we are unable to see beyond that obstruction.
When a light wave travels form air into water the quantity that remains unchanged it its speed amplitude wavelength or frequency?
When a light wave travels from air into water, its frequency remains unchanged. This is due to the fact that the frequency of a wave is determined by the source that creates it, and does not change when it passes from one medium to another.
What happens when light travels from one medium to another with a different index of refraction at a 0 degree angle of incidence?
When light travels from one medium to another with a different index of refraction at a 0 degree angle of incidence, it continues in a straight path without bending. This is due to the fact that there is no change in the speed of light when the angle of incidence is 0 degrees.
Why light travels slower in water than in air?
Light travels slower in water than in air because when light enters the water medium, according to the collision theory, the particles of the water gets some of the light energy and displaces light from its real path. As the energy is absorbed, it is a fact that on decreasing the energy of anything, it will get much slower in performing that work. So light travels slower in water than in air.

Why can't any shadow be there on moon?
There are no shadows on the Moon because there is no atmosphere to scatter light. On the Moon, sunlight travels in a straight line from the sun to the surface, creating sharp boundaries between light and dark areas, with no shadows being cast.
Why does light travel in straight lines give with evidence?
Yes there is. Your shadow is the simplest evidence that light travels in straight line. A solar eclipse is also evidence that light travels in straight lines, as is the fact that you cannot see around corners unless you use a mirror.
Why will you see light from an SOS out at sea before you hear one?
Because it is a known fact that light travels faster than sound.
Which property of light is illustrated by the fact that we cannot see around a corner?
The fact that we cannot see around a corner is due to the property of light called "line of sight." Light travels in straight lines, and when an object blocks our direct line of sight, we are unable to see beyond that obstruction.
What evidence do we have that light travel through a vacuum?
You create a vacuum in a lab, and then shine a light through it, and there is experimental proof that light travels through a vacuum. Alternatively, take the fact that light travels through space - if light could not travel through a vacuum, no light from the stars, the moon or the sun would ever reach our planet.
Why is earth not fully lighted?
Because the earth relies on the light from the sun. Only half of the planet can be lit at any time - due to the fact that light travels in straight lines.
Are all shadows black?
Yes... and No ...A shadow is caused by an object blocking light so that it doesn't reach a surface. The area in shadow appears black because there is no light falling on it -- it appears dark. In fact, most shadows aren't totally black, because light usually bounces around the obstruction off other objects (indirect lighting). You can also get coloured shadows where there are multiple light sources of different colours. e.g. in a nightclub or disco. Translucent objects may cast coloured shadows, e.g. stained glass in a church, where only some of the light has been blocked by the window.
What is happening When light passes through a transparent material it's direction is visually changed slightly?
That is called "refraction", and it is related to the fact that light travels slower in some materials than in others.
Why are shadows visible on the moon?
because the suns light still shins on the moon then the light just reflects of. The same rules apply on the moon in relation to light as does on earth. When something stands in front of a light souse then it will block the light and cast a shadow. the fact that there is no air makes no difference.
Whats faster sound or light?
Light is about 800,000 faster (compared to the speed of sound in air).
When a light wave travels form air into water the quantity that remains unchanged it its speed amplitude wavelength or frequency?
When a light wave travels from air into water, its frequency remains unchanged. This is due to the fact that the frequency of a wave is determined by the source that creates it, and does not change when it passes from one medium to another.
