Refraction is the bending of light as it passes through different mediums, while reflection is the bouncing back of light when it hits a surface. Refraction changes the speed and direction of light, while reflection maintains the original speed and direction. Both phenomena play crucial roles in how we perceive and interact with light.
In a microscope, reflection occurs when the light hits the specimen and bounces back, allowing us to see it. Refraction happens when light passes through the lenses of the microscope, bending the light rays to focus the image. Both reflection and refraction play crucial roles in forming a magnified image of the specimen being observed through a microscope.
Reflection is used in headlights of cars to increase visibility, while in photography, it is used to control the amount of light entering the camera. Refraction is used in eyeglasses to correct vision, and in lenses of telescopes and microscopes to focus light for magnification. Overall, both reflection and refraction play crucial roles in various daily life applications involving light manipulation.
The refractive index of water is 1.333. Refractive index n = c/v where c is phase velocity of a wave in a vacuum and v is the phase velocity of the wave in the medium. If precision is needed, then more variables come into play and n will change slightly. The temperature of the medium, the frequency of the light, etc... all can come into play.
The major divisions in a play script are called acts. The number of acts in a can range from one to five or more, depending on how a writer structures the outline of the story.

Refraction comes into play only when the light travels from one medium into another medium. The speed of light is different in different media, so the wavelength changes due to refraction. The formula for wavelength is the ratio of the speed of light to its frequency. The most important point is that the frequency character of light remains constant eventhough it travels in different media. Hence the wavelength is directly proportional to the speed of light. So as speed changes, the wavelength also changes accordingly.
When you wear glasses, the light is refracted so that your eyes can see images better. Microscopes and telescopes use refraction to change the perception of images. When you look into water and see objects in the water appear distorted, that is refraction.
The retina, specifically the fovea, is the main structure responsible for visual acuity in the eye. The fovea is a small area at the center of the retina with a high concentration of cone cells for detailed vision. The lens also plays a role in focusing light onto the retina for clear images.
Lots of things look different under water. As a result of refraction, the light that reaches us from the object under water changes direction.
