Can a luminous object be opaque?
Based on the above definitions we can classify the objects as opaque, transparent, translucent, luminous and non-luminous.
Is shadow luminous or non-luminous?
Luminous object: an object that gives out the light of its own is called luminous object. On the Luminous object: the object that does not emit its own light but only reflects the light of other sources. Shadow: an area of darkness formed by an opaque object obstructing light.
Which object does not form any shadow?
Translucent objects allow light to pass through them partially, while opaque objects do not allow light completely. Therefore, translucent and opaque objects can cast a shadow. All metallic objects are simply opaque in nature.
Which object can form shadow?
Answer: Among completely transparent and a translucent object only a translucent object will form a shadow.
Do luminous objects have shadow?
Illuminated Object Light falls on all the objects but not all the objects forms shadow. If you take a ball, its shadow is formed. But if you take the same ball in the dark room, you cannot see the shadow of the ball.
Do luminous objects have shadows?
What happens is these objects reflect the light which comes from the luminous objects when light falls on them. Light falls on all the objects but not all the objects forms shadow. If you take a ball, its shadow is formed. But if you take the same ball in the dark room, you cannot see the shadow of the ball.
Why shadow is formed?
Shadows are formed because light travels in straight lines. Shadows are formed when an opaque object or material is placed in the path of rays of light. The opaque material does not let the light pass through it.
Why shadow is not formed?
Formation of Shadows Shadows are always formed on the opposite side. Transparent objects cannot form a shadow. They are only formed in opaque or translucent objects. If we take a glass slab, no shadow is formed because it allows light to pass through it.
Which type of object forms Dark shadows Why?
A dark shadow is formed when an object blocks the light source. To form a dark shadow object should be opaque or translucent. Tree is opaque object and it can block the light from passing through it. Therefore when light falls on the tree it will produce a dark shadow.
Why does the shadow of an object form?
Shadows are formed because light travels in straight lines. Shadows are formed when an opaque object or material is placed in the path of rays of light. The opaque material does not let the light pass through it. The light rays that go past the edges of the material make an outline for the shadow.
What causes an object to form a shadow?
Shadows are made by blocking light. Light rays travel from a source in straight lines. If an opaque (solid) object gets in the way, it stops light rays from traveling through it. This results in an area of darkness appearing behind the object.
