Using control volume approach of projected velocity on any image(s) of your choice, explain why leaving the sunroof open only a few centimeters could be more catastrophic than leaving your side windows fully open during a rain storm (assume negligible wind).
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.
Using control volume approach of projected velocity on any image(s) of your choice, explain why leaving the sunroof open only a few centimeters could be more catastrophic than leaving your side windows fully open during a rain storm (assume negligible wind).
To analyze the situation using a control volume approach, let's consider a hypothetical car moving with constant velocity through a rainstorm.
The dashed lines represent the boundaries of the control volume, which is a region of space that encloses the car and the raindrops that are falling onto it. The projected velocity of the control volume is the velocity with which the raindrops are hitting the car. It is equal to the component of the car's velocity that is perpendicular to the surface of the car.
Let's assume that the car is moving from left to right, and that the side windows are fully open, while the sunroof is only open a few centimeters. In this case, the projected velocity of the control volume will be different for the two openings.
