Which of the following pair is correct? I. Opaque - do not allow light to pass through them II. Translucent - allow light to pass through them partially

Which of the following pair is correct? I. Opaque - do not allow light to pass through them II. Translucent - allow light to pass through them partially Correct Answer Both I and II

Explanation:

  • Transparent materials: Objects that allow light to pass through them and help see things clearly through them are called transparent materials.Example: Glass, Water etc.
  • Opaque objects: Objects that do not allow light to pass through them and prevent see-through are called opaque objects. Example wood, plate, iron rod, etc.
  • Translucent objects: Objects that allow the most light to pass through them (but not whole) and help in seeing things partially through it are called translucent objects. Example: filter paper. 
  • So both I and II are correct. 

Additional Information

  • Light is an electromagnetic wave that produces the sensation of vision. 
  • The wavelength of the visible spectrum lies between 400 nm to 700 nm.
  • The object that emits their own light is called luminous objects. Example Sun, Blub, Candle, etc. 
  • Reflection is the phenomenon of bouncing back of the light. 
  • Light bends its path when it travels from one transparent medium to another. That is called Refraction of Light.

The human eye is a complex part of the body that is used for seeing. Eyes enable people to perform daily tasks and to learn about the world that surrounds them. Sight, or vision, is a rapidly occurring process that involves continuous interaction between the eye, the nervous system, and the brain. When someone looks at an object, what he really sees is the light reflected from the object. This reflected light passes through the lens and falls on the retina of the eye. Here the light induces nerve impulses that travel through the optic nerve to the brain and then over other nerves to muscles and glands.
The eye is similar to a television camera. Both the eye and the television camera convert light energy to electrical energy. The eye converts light to nerve impulses that are interpreted by the brain as the sense perception called sight. A television camera converts light to electronic signals that are broadcast and transformed into light images in a television receiver. It is wonderful that human eyes blink an average of once every six seconds. This washes the eye with the salty secretion from the tear or lachrymal glands. Each tear gland is about the size and shape of an almond. These glands are situated behind the upper eyelid at the outer corner of the eye. After passing over the eye, the liquid from the gland is drained into the nose through the tear duct at the inner corner of the eye. The sense perception that the brain releases after the eye converts light to nerve impulses is known as
