Why Is The Shipbuilders So Unsinkable

Newton’s knowledge of light helped him build the first reflecting telescope (Bortz 13). Newton proved his theory of light and color with the use of his reflecting telescope (Allan 45). In 1672, Newton published his notes on lights and color (Allan 54). Another scientist, Robert Hooke believed that light waves made up light (biography). The scientific community ultimately agreed with Newton’s theory. Newton’s study of light helped him figure out that a beam of light can turn into a spectrum of colors (Pascal 44). Using a drop of water and a light prism, Newton discovered that when white light bent, all colors were visible (Steele 31). Galileo and Descartes influenced Newton on the subject of inertia (Christianson 38). A falling apple helped Isaac with his theory that gravity pulls things down (Pascal 48). The strength of gravitational force is determined by the mass and distance of two objects. (Steele 49) The force of gravity lies between the centers of each object. (Steele

B. Sir Isaac Newton used prisms to show that sunlight was made up of all the colors of the rainbow. This proved that the ancient Greeks ideas about light were wrong.

Color is determined by the lengths of waves of light. Although there is no sure way to fully tell how we actually perceive color, there are two theories that seek to explain so. One is the trichromatic and the other opponent-process. Whereas one theory lacks in explaining a key problem the other succeeds, which is the case of the trichromatic theory and afterimages. Although the trichromatic theory does not explain the phenomenon of afterimages, of the two theories, the trichromatic one best explains how we see color.

When a beam of sunlight passes through a specially shaped glass object called a prism, the rays of different wavelengths are bent at different angles. The bending breaks up the sunlight into a beautiful band of colors. This band contains all the colors of the rainbow and is called the visible spectrum. At one end of the spectrum, the light appears as violet. It consists of the shortest wavelengths of light that we can see. Farther along the spectrum, the light has increasingly longer wavelengths. It appears as blue, green, yellow, orange, and red, each shading into its neighboring colors in the spectrum. The longest wavelengths of light that we can see appear deep red in color. Some descriptions of the spectrum also mention the color indigo, which is closely related to blue, between violet and blue.

1800 – William Herschell was a contemporary of Sir Isaac Newton and was fascinated with one of Newton’s recent discoveries. Newton posited that when light was refracted through a prism, different colors of the visible light spectrum were

2- It is impossible to identify all element with the naked eye because they don’t release enough energy, therefore the color is not as visible. Besides, not all elements give a light that it is in the visible part of the spectrum, so we need to use a prism.

“Those colors are from sulfur and iron oxide mainly,” Norval said, revealing more of his encyclopedic knowledge of Gnaritus’ geology. “There are many colorful rainbows on Gnaritus not only in the sky but also on the land!”

1.) List all of the colors found in the visible light spectrum (We covered this in lecture)

Measurements were taken of reflection and refraction angles from the vertical, speed and wavelength. It was noticed that if light was shone at several prisms, at a certain angle, colours of light were refracted. Some of the colours refracted differently due to their different speed and wavelength. Through the computer test, it was found that when light moved from an area of low density (eg air) to high density, the angle of refraction was decreased. For example, what was tested was light going through air to water ( low to high density) with the angle of vertical being 30 degrees.

A rainbow is caused by the reflection, refraction and dispersion of light in water droplets resulting in a spectrum of light appearing in the sky. . It takes the form of a multicolored arc; Rainbows caused by sunlight always appear in the side of sky directly opposite the sun. A primary rainbow the arc shows red on the outer part and violet on the inner part.

Over time, the silicate-rich solution settles and the water evaporates, forming layer upon layer of silica spheres. The layers of precipitated silica spheres turn into a jelly-like water mass, producing a diffraction grating when the spheres are even in sizes and well-ordered. This creates a ‘play of colour’ from within the stone when it is moved and the light hits the spheres in different angles.

3) If you were looking for a rainbow in the morning, which direction (N, S, E, W) would you face and why?

The “unsinkable” Titanic’s maiden voyage was a disaster because she split in two from crashing into an iceberg. 1,517 people died from the horrible tragedy, only 706 people survived.

The speed of the wavelength of white light before it hits the raindrop determines the color a raindrop will emit. If the wavelength of white light travels at a slow speed, then the wavelength of light will bend more when it enters the raindrop.
