Chrichment lamp light Reflective Angle 30 When a beam of light strikes a mirror, it is reflected at the same angle as it hits. The diagram on the right shows how the light from the lamp strikes the mirror at a 30° angle. It reflects into the boy's eye at the same level. 30 reflected light Alvin Alvin knows about the reflective angles of a mirror. He decides to use this method to measure the height of the building to see how long a ladder will be for him to reach the roof. Alvin has a mirror and a meter stick. 1 Find the similar triangles in the illustration. 2, What measurements does Alvin have to make? Oロロロ 3. Assign some measures to your illustration. Let x be the height of the building. 4. Write the proportion and solve for x. 5. Look for the tallest tree in your school campus and find its height using the method presented above. Mrin Facus
Refraction of Light
Refraction is a change in the direction of light rays when they travel from one medium to another. It is the bending of light when it goes through different media.
Angle of Refraction
Light is considered by many scientists to have dual nature, both particle nature and wave nature. First, Particle nature is one in which we consider a stream of packets of energy called photons. Second, Wave nature is considering light as electromagnetic radiation whereas part of it is perceived by humans. Visible spectrum defined by humans lies in a range of 400 to 700 nm wavelengths.
Index of Refraction of Diamond
Diamond, the world’s hardest naturally occurring material and mineral known, is a solid form of the element carbon. The atoms are arranged in a crystal structure called diamond cubic. They exist in a huge variety of colours. Also, they are one of the best conductors of heat and have a very high melting point.
