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.
Add a small amount of sodium carbonate to a beaker. Record physical properties of hydrochloric acid and sodium carbonates appearance. 2. Write a hypothesis on what you think will happen when they are mixed. 3.
A coin needs to be used to extract pigments from the spinach leaf cells. Place a small section of the leaf on the top of the pencil line. Then place the chromatography paper in the cylinder so that the pointed end is barely in the solvent, make sure not to get the pigment in the solvent. Mark the bottom of each pigment band. Then measure the distance of each pigment starting at the bottom of the pigment origin to the bottom of the separated pigment band.
I would then untwist the wires and put them in the correct color order that I need. Then I would flatten out the wires and in one hand hold my RJ-45 connector and then with the other hand feed the wires into the connector. This is usually pretty simple with the way the connectors are made, and they are also usually clear. After I’m sure that the wires are in the connector all the way, and in the right order, I would use a wire crimper to clamp[ the wires securely in to the connector. Coaxial cable- For the COAXIAL CABLE I would do the same first few steps by getting the correct length of cable that I would need.
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.
4) Next, we will construct a box that is a little larger than the egg with the remaining poster board. a) Trace 4 outlines of the egg on to the poster board. b) Cut out a rectangle around each of the egg outlines. (See figure 1.2.) Figure 1.2 c) Tape the 4 rectangles together in the shape of a box.
AP Physics C Lab Report i. Purpose: To use derivatives to investigate the various characteristics of cardboard ii. Materials: Compass, Cardboard, mass balance, ruler, meter stick iii. Procedure: 1. Measure and record the diameter of each of the disks in meters.
In the center the strips, about 3 cm from one end, place a dot of the marker to be tested. The dots should be about 0.2 cm in diameter and dark enough to be clearly visible. Place about 2 cm of water in each glass. Tape the unmarked end of each strip to the center of a pencil so that the strip hangs down when the pencil is held horizontally. Carefully insert the strips into the glasses, dotted end down.
* Hold the flat surface of the scribe tool flat against the ferrule tip with the beveled edge facing up. Carefully score the fiber close to the intersection of the ferrule tip and fiber. Score on one side only. * Remove the excess fiber with a straight, non-twisting pull and deposit in a safe place (i.e. onto a piece of tape or in the debris container).
A wet swab was used to collect a small sample of the compound. The swab was placed over a Bunsen burner and the flame’s color was recorded. The flame test color of the unknown cation was then compared with the known cations, listed
