Trick question or a question asked by someone who doesn't truly understand the issue.
One can say that colorless polished glass or clear plastic has no shadow. Probably the answer your teacher is seeking.
But this is not true. Even glass is not perfectly transparent and casts a small shadow. Perhaps a shadow barely perceptible to the human eye, but it is there.
It is possible to have a luminous solid object emit the exact amount of light to cancel its shadow, but this isn't really having no shadow, is it?
Your teacher will not like this answer.
If we REALLY want to confuse them, we can speak of metamaterials.
What else can I help you with?
What shadow appears when light hits an opaque object?
When light hits an opaque object, a shadow is created on the opposite side of the object where the light is blocked. The shadow is a dark area where light cannot pass through due to the solid nature of the opaque object.
What is the direction of a shadow?
A shadow is formed in the opposite direction of the light source. For example, when the light source is behind an object, the shadow is cast in front of the object.
Can the shadow of an object be bigger than the object itself?
Yes, the shadow of an object can be bigger than the object itself depending on the angle and intensity of the light source. For example, if the light source is close to the object and the surface on which the shadow is cast is far away, the shadow can appear larger than the object casting it.
Why does a shadow form behind an object when light shines on it?
Because a shadow forms behind an object when a light source shines on it. This happens because the object is solid and light can not travel through the solid object. The light that travels around the object reflects back up and the area that is not reflecting looks darker. That's why! Did this help you?
Is solid an adjective?
Yes, "solid" can function as an adjective when describing something firm, stable, or strong. For example, "solid foundation" or "solid object."
How is a shadow produced?
Shadows are formed when light shines on an opaque (solid) or translucent (partially solid, like a net curtain) object. This object stops the light rays, so a shadow is produced in the shape of the object. For example, if you hold your hand in front of a light, then the light will only be seen in the places where your hand is not blocking it. You will then see a hand shaped shadow.
Can a solid object cast a shadow?
Yes, as long as it is in the right position of a light, it will reflect a shadow. Even if it is glass it will show a light shade of a shadow :)
Does a mirror form a shadow in the dark?
Shadows can only form when there is light present. A shadow is the result of a solid object blocking visible light. As a mirror is a solid object it can indeed produce a shadow, but nothing can form a shadow in the dark, there must first exist a light source.
What shadow appears when light hits an opaque object?
When light hits an opaque object, a shadow is created on the opposite side of the object where the light is blocked. The shadow is a dark area where light cannot pass through due to the solid nature of the opaque object.
What is the direction of a shadow?
A shadow is formed in the opposite direction of the light source. For example, when the light source is behind an object, the shadow is cast in front of the object.
When light falls on an object which side do shadows fall?
The shadow will fall on the opposite side that the light hit the object. Assuming that the object is a solid object that you cannot see through, there would be no light on the other side, hence causing the shadow.
Can the shadow of an object be bigger than the object itself?
Yes, the shadow of an object can be bigger than the object itself depending on the angle and intensity of the light source. For example, if the light source is close to the object and the surface on which the shadow is cast is far away, the shadow can appear larger than the object casting it.
Why shadows exist?
A shadow is cast when sunlight is blocked by a solid object - a person, a post, etc.
Why does shadow grow?
Because he absorbs or reflects light like any other solid object. Yes that and the fact that everyone and everything will have and always has had a shadow.
Why does a shadow form behind an object when light shines on it?
Because a shadow forms behind an object when a light source shines on it. This happens because the object is solid and light can not travel through the solid object. The light that travels around the object reflects back up and the area that is not reflecting looks darker. That's why! Did this help you?
How does the position of the sun in the sky relate to the length of the shadow cast by an object?
The position of the sun relates to the length of the shadow cast by an object because, when the sun is above the object there is no shadow yet, when the sun is say to the east of the object a shadow is cast towards the west, the farther the sun for example east the longer the shadow will be towards the west.
What is the height of the shadow when the distance from the light source to object is 24cm?
It depends what angle the light is at, for example the shadow would be longer if the light was looking atr the object from the side (45 degrees) than it would be if looking at it from the top of the object(180 degrees).
