Physics lab analysis pdf

Record the both the heights and focal lengths of the objective and eyepiece lenses and determine the barrel length, L, as the distance between the two lenses. Paste a copy of your graph into your e-journal.

Construct and describe a telescope, include images of the telescope. Where any two rays intersect, the image is formed. With the screen at the same position move the lens toward the screen until a second sharp image is formed on the screen and repeat the above steps. Two converging achromatic lenses with focal lengths of about 6 cm and 13 cm Physics lab analysis pdf Analysis software Vertical rod in table-top stand Printed arrow Font size 11 Smart phone with camera or webcam Support ring for Phone Physical Principles: Place the carriage with the screen at the cm position.

Clamp a lens holder at approximately 7. Why might the approximate expression for the magnification of a microscope be somewhat inaccurate?

Next draw the three reference rays: Place the carriage on the optical bench and position it so that the fiducial mark is as near 0 cm as possible. For a converging lens, the focal length is always positive, for a diverging lens it is always negative.

What parameters of your microscope could be changed to enhance the magnification? This should be done to scale so that the position and size of the resulting image are accurate. Converging Lens Setup Place an object slide together with an aperture into a screen holder and insert the holder rod into a carriage.

Focal Length For the rays shown in Figureslight is assumed to be coming from the left, and going toward the right. If the D2L site is down, email the completed report file directly to a lab TA or to physics andrews.

Then locate the position of the two focal points and the object. Have your ID card ready to scan to receive credit for your explanation.

The Central Ray 2 proceeds straight through he center of the lens. Record the position of the lens as xL and the position of the screen as xS. Repeat this until the screen is at 60 cm.

Reference rays originate from the object, travel through the lens and are refracted. You should have a barrel length around 30 cm. Place the carriage with the small 13 cm achromatic lens on the optical bench at about 50 cm or the middle of the bench. Is the image on your screen real or virtual?

Read a photo file into Paint and zoom as much as desired.

Do this for both the magnified and unmagnified images. A converging lens always has two focal points, the primary focal point on the near side of the lens towards the oncoming light rays and a secondary focal point on the far side of the lens away from the oncoming light rays. Sketch a simple diagram of your microscope set up.

Use a light source across the room or out the windowas far away as possible - at least 50 times the focal length, and direct the light from this source through the 13 cm converging lens onto the projection screen.

Move the lens away from the screen until a sharp image is observed. See Figures 1 and 2. Parallel light rays approaching a converging lens will converge at the secondary focal point.

Email both photos to yourself for analysis in Microsoft Paint. Sketch a simple diagram of your object, lens, and screen set up. Include a photo of your microscope in your e-journal report. The Focal Ray 3 is drawn towards the focal point then refracted parallel to the axis.

The third ray should pass through the same intersection point; this just confirms the location of the image.University of TN Chattanooga Physics L 8/21/ PHYSICS L LAB LAB 2: OHMS LAW LAB.
