網頁This is the clear, dome-shaped surface that covers the front of the eye. From the cornea, the light passes through the pupil. The iris, or the colored part of your eye, controls the amount of light passing through. From there, it then hits the lens. This is the clear structure inside the eye that focuses light rays onto the retina. 網頁The microscope is basically an optical system (for magnification) and an illumination system (to make the specimen visible). To help understand the function of the various parts of the microscope, we will follow a ray of light as it works its way through a microscope from the light source, through the lenses, up to the eye.

This candle can help us understand how the eye captures images and then sends them to the brain.First, the candlelight passes through the cornea. As it does, it's bent, or refracted, onto the lens. As the light passes through the lens, it's bent a second time.

網頁Step 1: To start with the diagram, the students should draw a convex lens and place an arrow-like object beyond the 2f distance from the lens. Now, the students need to take three incident rays from the top part of the object. These three rays will travel towards the lens, and one of them passes through the focus. 網頁See Answer. Question: 1.
