How does a microscope work?

Answer 1

Light waves are bent as they travel through glass increasing the ability to see items at a much more magnified level.

First, we have to light up the specimen. A mirror mounted under the microscope stand does the job. Light bounces off the mirror, passes through and around our specimen (mounted firmly to a microscope slide), and into the objective lenses. These lenses bend some of the spread out light beams from the specimen into straight line paths that travel through the microscope tube. Next, the light beams reach the eyepiece lenses. These lenses bend the light back into your eye, so you can see the specimen up close.

Answer 2

An Acoustic microscope works by using sound waves instead of beams of atomic particles. The echoes of sound waves bouncing off the specimen are translated onto a screen as a microscopic image. Even though the sound waves are used in high frequency, they do not damage living things.

Answer 3

A camera lens uses refraction to focus light on the film, or in a digital camera on the CCD or other light-sensitive array.

When a ray of light passes from a less dense to a more dense medium (such as from air to glass) it slows down. If it strikes the glass surface at an angle, it is also bent a little, and this is called refraction. When it passes back into air, it speeds up again, and is again refracted if the surface is at an angle.

The interesting thing happens when the light rays are parallel to each other but not parallel to the axis through the centre of the lens. Just take it on trust for a moment, this same lens will also focus these, but to a point above, below or beside the focal point for rays along the axis, and all these points of focus of parallel rays will form a plane, called the focal plane of the lens. So, you put the film at this focal plane, and you've now used the lens to concentrate the light on the film, and form an image.

Answer 4

a lens works when light goes through it and refracts (bends) inside the lens. so the light
