Internal structure of eye

The internal structure of the eye includes the following parts:

Retina: It is the screen at the end of the eye, where all the images are formed.               It .....

Retina is another layer of eyeball. The retina  focuses an image of what is in front of the eye. The optic nerve carries signals from the retina to the brain, which interprets them as visual images. The retina has two types of cells the rods .....

2. Middle ear:  It consists of tympanic cavity and                           chain of three small bones called ear ossicles— the malleus (hammer shaped),     .....

The photoreceptors in the retina convert the light into the electrical signals. These signals are carried to the brain by optic nerves and nerve fibres. The brain then translates the electrical signal into images we see. The image we receive on .....

With the vibration of the last bone the stapes, the fluid within the inner ear cochlea is moved. Thus the cells generate an impulse in the system of inner ear ( coclea ). The sound vibrations activate tiny hair cells in th inner ear, which in .....

You know that a light bends from normal as it passes from one medium (water) to another (air). Here, the light coming from the fish refracts (changes direction) when it hits the surface. Due to this, a fisherman who is above the water sees .....

Refraction of light from water to air or air to water gives apparent position of things in water. In a pool, refraction of light makes pool appear shallow. However, the pool is deeper than it actually appeared. So, it is dangerous to go in the .....

When we look at a coin placed in water, the light coming from coin bends away from normal. And we look as if the light from coin is coming straight. This gives apparent position of the coin. The apparent position seem closer to eyes. Thus, a .....
