B. Measure sides a, b, and c of the triangle with a tape measure and record these values in centimeters (cm) on your data sheet. C. Measure angles A and B of the triangle with a protractor and record on your data sheet. D. Using the values for the sides of the triangle that you measured in Step B, compute angles A and B by using the different trigonometric functions. E. Calculate the average value of the computed angle A by adding the three computed values of A and dividing by 3.
Andrew Knapp Unit 7 Assignment 1. Refraction, Reflection, and Optics NT1310 2/18/2015 Refraction occurs when there is a change in direction of propagation of a wave due to a change in its transmission medium. Basically this is when light is bent due to the light waves passing through a substance such as water or glass. When this happens the light particles slow down or are absorbed into the material. A real life example of refraction would be when a pencil is placed halfway in a glass of water.
Use a protractor to measure the angle from the reference line to the lines drawn in step 6. 8. Record the angle created by the laser pointer through the air as the Angle of Instance and the angle created by the laser pointer through the water as the Angle of Refraction. 9. Use Snell's Law to determine the Index of Refraction of Water.
Measure and record the diameter of each of the disks in meters. 2. Mathematically record the radius of each of the disks as well. 3. To measure the circumference of the disk, make a mark on the disk and place the disk on the meter stick with the mark coinciding with a meter stick reading.
Objectives: The purpose of this lab is to observe the reaction of crystal violet and sodium hydroxide by looking at the relationship between concentration and time elapsed of the crystal violet. CV+ + OH- CVOH To quantitatively observe this reaction of crystal violet, the rate law is used. The rate law tells us that the rate is equal to a rate constant (k) multiplied by the concentration of crystal violet to the power of its reaction order ([CV+]p) and the concentration of hydroxide to the power of its reaction order ([OH-]q). Rate = k[CV+]p[OH-]q To fully understand the rate law, concentrations of the substances must be looked at first. The concentration is measured in molarity.
It bends or refracts light rays entering the eyes. C. It is the site of attachment for the extraocular muscles. D. It helps to maintain the shape of the eye. Answer Key: B Question 2 of 20 1.0 Points The border between the transparent edge of the cornea and the white of the fibrous sclera is the: A. pupil. B. anterior chamber.
How do you know? In Part II the reaction you observed was: HSO4- (aq) + H2O (l) → H3O+(aq)+SO42-. Compare the colors you observed in the experiment and answer these questions: A. Which way should the equilibrium shift when Na2SO4 is added? How do your results support your answer?
Aim: The aim of this experiment is to understand reflection and refraction and how they vary with different matters. Data/Results: The hand drawn images are attached to this lab on a separate sheet of paper. Questions: 1. Based on both of your observations on reflection, what can you say about the relationship between the angle of incidence and the angle of reflection? The angles of incidence and reflection are both the same.
Add hydrochloric acid to a test tube. Cut a piece of magnesium ribbon (couple of centimeters). Record the physical properties of both substances. 2. Write a hypothesis on what you think will happen when mixed.
Liam Stephenson controlled assessment Introduction In my course work I will be looking at how the thickness of a converging lens affects the focal length. The factors involved in this experiment are: light, lens curvature, refraction and thickness of the lens, these will determine the focal length; the focal length is the length between the focus and the lens. Light-visible light is an electromagnetic wave in the electromagnetic spectrum The speed of light depending on the medium it is in, for example the speed of light is 300,000 km/s however when light travels through other medium such as water or glass the speed of light is slowed this is because water and glass is denser than a vacuum of air. Due to it being more dense and a change in speed, the direction of the wave will change this is
