Case Example: Compute for the number of images produced by a 2 separate mirrors at an angle of 60 degrees if the object is placed between the mirrors. N = (360°/60°) - 1 = 6 - 1 N = 5 images Kindly answer 1 and 2 1. Compute for the number of images produced by a 2 separate mirrors at an angle fo 45 degrees if the objects is placed between the mirrors
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.
Case Example:
Compute for the number of images produced by a 2 separate mirrors at an angle of 60 degrees if the object is placed between the mirrors.
N = (360°/60°) - 1
= 6 - 1
N = 5 images
Kindly answer 1 and 2
1. Compute for the number of images produced by a 2 separate mirrors at an angle fo 45 degrees if the objects is placed between the mirrors.
2. A sight testing chart measuring 120 cm x 80 cm, the long dimension being the vertical one is to be viewed by reflection in a plane mirror. Find the smallest size of the mirror that can be used if the chart is 3.25 meters away from the mirror and the observer's eye is 2.75 away from the mirror. The lower edge of the chart is 1.5 meters above the ground. How high must the edge of the mirror the ground?
