Write a 2 page essay on Path of Light.
Light travels in a straight path at 300, 000km per second or at proximately 186, 000miles per second. however the velocity of light is considered slower in glass and water (Katz, Small and Silberberg, 2012). Objects and devices prevent the travel of light in a straight line causing refraction commonly referred as the bending of light (Minnaert, 2013).
In the first experiment testing the movement of light in a straight line without any obstruction or not encountering any interface, the light path is considered extremely straight. Thus, it is deduced that whether light travel in water, air, glass, and diamond or any other object it moves in the straight line until it meets an object or a different medium. It is believed that it travels a constant speed c referred to as the speed of light. This c is calculated to be 300,000 kilometers per second (Katz, Small and Silberberg, 2012).
It is realized that light is emitted or reflected by visible objects. It is also noted that when objects reflect light, it moves in all directions. It is believed that the reflected light forms the image in our eyes (Fleming, Jäkel, and Maloney, 2011).
The path of light is regarded straight, and it is belied to travel at a constant speed in a uniform material until it encounters an object or another material. In the first experiment, it is shown that light travel straight until it meets another object where it becomes refracted making it bend (Katz, Small and Silberberg, 2012).
In the second experiment, we make a pinhole viewer that is used to allow light from the source through small holes made in the aluminum foil. When viewed through it is realized that there is a bright light on the tape that creates an image (Minnaert, 2013).
In conclusion, the experiment shows how light travels through objects. Besides, it shows how light travels in a straight line unless destructed by objects where it is emitted (Katz, Small and Silberberg,
