An image is formed by the refraction of light at a spherical interface between two media of indices of refraction n1 and n_2. Image distance depends on the radius of curvature of the interface, location of the object, and the indices of refraction of the media.

Yet another aspect is that, because of dispersion, the light from the star – especially if it is low down near the horizon − will be drawn out into a short spectrum, with the red end closer to the horizon than the blue end, and there is then a problem of how to measure the position of the …

By incorporating these strategies and activities, educators can effectively teach 10th graders about reflection and refraction of waves, helping them understand and appreciate these fundamental concepts and their applications in the real world.

The color of the rays is to help distinguish the rays, and is not meant to indicate any color dependence. (CC BY-SA 3.0; Clément 421138).

At the summer solstice, the Sun is higher in the sky and its rays strike Earth more directly. The Sun is in the sky for more than half of the day and can heat Earth longer. At the winter solstice, the Sun is low in the sky and its rays come in at more of an angle; in addition, it is up for fewer than 12 hours, so those rays have less time to heat.

(Some of the incident light is reflected from the surface, but for now we concentrate on the light that is transmitted.) The change in direction of the light ray depends on the relative values of the indices of refraction of the two media involved.

For instance, when you look at a fish from above the water surface, the fish is in medium 1 (the water) with refractive index 1.33, and your eye is in medium 2 (the air) with refractive index 1.00, and the surface of the water is the interface.
