Physics Key Points

Light waves are a form of electromagnetic waves, which consist of patterns of electric and magnetic energy. The visible spectrum is only a small part of the electromagnetic spectrum-the

attributes. The optical effect may be explained by the fact that the human eyes see an object

Molecules are still in motion, but there is no net change when dynamic equilibrium is reached.

We benefit greatly the benefits of long distance communication, eating food from different parts of the countries without fear of spoilage, radiation treatment, and heating up food in a matter of minutes, and a myriad of other wonders all do the wonders of waves, be they sound waves as well as light waves. In this timeline, we will look at all of the different light waves, their history, and their benefits.

block is moving with a speed of 6 meters per second. What is the magnitude of the unknown force?

Force is equal to the mass of an inert object multiplied by the acceleration of that body

The colorful look of dichroic glass is only achievable through thin film physics, and process that gives bubbles their rainbows and dragonflies their colorful wings (Smedley). In occurs when one light wave hits a thin film. Part of the wave is reflected as some continues to travel through the film, diffracting slightly as it enters the new medium. The continuing wave then encounters another new medium where it is reflected back. This reflected wave then interferes with the first reflected wave. This causes the colorful spectrum that can be seen in a dichroic glass

Light passed through a transmission grating is often sent in all directions due to interference. The grating acts as a new wave source and causes the light to travel in different paths. Equation 1 below shows the relationship between path difference and light direction due to constructive interference. D represents the line spacing and sinƟ=a/c according to the drawing below.

If the size of the marble was bigger, the shape would appear to be smaller and if the size of the marbles were smaller, the shape would appear to be bigger. This is because as the size of the marbles changes, so does the angles that they make, when they bounce off of the shape. This angle size depends on the speed and size of the marbles and when one of those variables are changed, it can make it difficult to determine the position and shape of the

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.

Feedback: The correct answer is b. Symmetry is the exact duplication of elements (shapes, forms, etc) on either side of a (usually imaginary) straight-lined central axis.

2) What is a mirage and why does it always disappear as the observer gets closer?

Light is electromagnetic radiation, energy shown as a wave or a particle, that can be visually perceived as radiant energy.1 Light is measured by the wavelength and frequency. A wavelength is the distance from any point on one wave to the same point on the next wave and shown by lambda, λ.2 The different types of light begins with gamma rays and proceed to radio waves when increasing wavelengths are compared. Frequency is the number of crests per second and is expressed in hertz and shown as v. The pattern associated with light is indirectly related to the wavelength. The variability of light starting with gamma rays and ending with radio waves is connected by decreasing frequency. Frequency is independent of the wavelength and are both

2. Yes, my right hand does experience a force. When I pull with my left hand I do add force with my

When the Sun's light is refracted on passing through tiny rain droplets falling in the air a Rainbow is formed. Rainbows only need light from the sun or the moon and a large amount of spherical raindrops to form in the atmosphere. The rainbows can be compared to mini prisms. The light is refracted ("bending of light as it passes from one medium to another") and it causes different wavelengths (or colors) of the white light to separate. Whether these wavelengths of light will pass through the raindrop or reflect depends on the angle the light strikes the back of the raindrop. If a wavelength of the light strikes the back of the raindrop at an angle less than 48 degree relative to the normal then the light will pass through the raindrop.
