Wavelength

Through the fields incorporating the science of light, astronomers use factors such as wavelengths to interpret stars’ temperature, heat, distance, size, mass, density, etc. To obtain all of this information certain light gathering instruments must be used. These instruments include telescopes. To record this information spectrographs are also mainly used to record the spectrum and dispersion of light. In light there are different waves and particles. Light is made up of electric and magnetic

The wavelength of the wave the distance between the peak of one wave and the peak of the next, between the minimum of one and the minimum or the next, or between any two points the encompass one complete wave cycle. Equivalently, this is the distance the wave travels from when say the electron is at the peak of its motion and the next time it gets to the peak of its motion. Either way this is about 10 or so grid points. 5) If the amplitude is increased, what happens to the wavelength?

light of certain specific wavelengths of light than deoxygenated haemoglobin and vice versa. Two wavelengths of light are used in pulse oximetry, red light of approximately 600nm, and infrared light with wavelengths of approximately 900nm. These two wavelengths of light are used to differentiate between two different substances, each with their own absorbance characteristics. b) When performing pulse oximetry there are various substance that will absorb both wavelengths of light, including the venous

The wavelength of the sound produced was computed. 2 more trials were made and the average wavelength was computed. By using the average wavelength and the frequency engraved in the tuning fork, the velocity of sound in air inside the glass tube was compted. The temperature was then determined and the speed of sound was then

PHY112 – Lab 9 – Worksheet Directions •When you go to the simulation you will have a choice to either run the simulation or download the simulation. Run may not work on all computers. If it does not run, download the simulation and work from there. •When the simulation opens, play with the controls and buttons to become familiar with how the simulation works. •Note: A formal lab report is not required for this activity. You may cut and paste this worksheet to a new Word document and adjust the

If light is shone at various mediums with varying densities then the light will bend more with different speeds, wavelength and angles. Learning about bending light is important because when the aliens invade our planet earth they will bring, as NASA predicted, tons and tons of light based weapons. In order to stop the aliens you need to know how to bend the deadly light away from our planet for it to be saved. A computer was used to simulate light being shone through water, air, glass

the experimental value of the wave speed. Th linera mass density value will be given to you by your instructor. Record your calculations in your data table. Next, using excel, construct a graph of wave speed as a function of wavelength. Use your values of the full wavelength as the values for x and the values of the calculated velocity for the y values in your graph. After plotting, set a trend line and display the equation of the graph. The slope of the line will be the calculated experimental value

from traditional radar in several important ways. First, because OCT uses a much shorter wavelength of light than radio-frequency radar, OCT emissions only propagate about 1 mm into biological tissues. This limits the possible images from OCT as compared to MRI or CT scans, so OCT is only appropriate for some specific types of medical imaging, such as retinal scans. The benefit of using a shorter wavelength is an increase in imaging resolution. A typical OCT image has a resolution of 10-20 µm. At

| Assignment 2 | Guide wavelength measurements | | | Abstract The purpose of this experiment is to demonstrate: a) The techniques for measuring guide wavelength. b) The relationship between the wavelength in free space and the guide wavelength. Furthermore, this experiment will be a way in which to gain experience in using different types of laboratory communications equipment. Introduction What is wavelength? Wavelength of a sinusoidal wave is the distance between identical
