Which material would form a darker shadow translucent or opaque Why?

A material that partially allows light to pass through it is called translucent material. A material that do not allow light to pass through it is called opaque material. When opaque objects are placed in the path of the light, a dark portion is formed on the opposite side of the object.

Will a translucent or opaque object form a darker shadow?

Answer: Among completely transparent and a translucent object only a translucent object will form a shadow. Shadow formed by an opaque object will be darker than a translucent object.

What is required to get a shadow of a opaque body?

Explanation: Those objects which don’t allow the light to pass through them are called as opaque objects. When the light hits the opaque object it gets refracted and thus doesn’t produce image. For shadow formation, a light source is required.

Is a shadow opaque?

A shadow is a dark (real image) area where light from a light source is blocked by an opaque object. It occupies all of the three-dimensional volume behind an object with light in front of it. The cross section of a shadow is a two-dimensional silhouette, or a reverse projection of the object blocking the light.

What kind of shadow is formed by opaque object?

Answer:

Image Shadow
An image is formed when the light rays are reflected from a mirror or any shining object. A shadow is formed when the path of light rays gets obstructed by an opaque body.

Which factors could change the size of the shadow of an opaque object?

– The size of the shadow is mainly dependent on the distance between the main object and the main light source. – In terms of horizontal light source placement the distance with the light source is inversely proportional with the length of the shadow of that object.

What material makes the best shadow?

Transparent materials let most of the light pass through. Translucent materials allow some light to pass through. Transparent and translucent objects still form shadows, but they may be faint, fuzzy or coloured.

What does a shadow represent?

A shadow itself represents the blocking out of light and, therefore, implies the existence of some lurking darkness or source of evil.

Is there any use of shadow?

What is the difference between light and shadow?
