By analyzing the video and utilizing available tools, the focal length of the concave mirror in trials 1-3 was determined.
To determine the focal length of the concave mirror, several steps were followed using the video and available tools. First, the video was observed carefully to identify the setup and measurements. It was noted that the concave mirror was used to reflect light from a distant object onto a screen. The position of the screen and the mirror were measured from the setup.
Next, the formula 1/f = 1/u + 1/v was applied, where f represents the focal length, u represents the object distance, and v represents the image distance. The object distance was measured as the distance between the object and the mirror, while the image distance was measured as the distance between the mirror and the screen.
By substituting the measured values into the formula, the focal length of the concave mirror for trials 1-3 was calculated. It is important to note that multiple trials were conducted to ensure accuracy and account for any experimental variations. The calculated values were then compared and analyzed to determine the average or most consistent focal length.
Complete question :-
1. Use the video and the available tools to determine the focal length of ONE of the concave mirrors from trials 1, 2 and 3. Report which Trial you analyzed, and describe the process you used to find the focal length. If you prefer, you can upload your handwritten work as high-quality images (approx. 600 x 400 pixels works best). Use the following format, with 1-2 sentences for each part: Summary: Trial number and focal length, with + uncertainty (and units, of course!). Include a cropped screenshot of the still image from the video showing the intersecting rays. (Not too big! 600 x 400 pixels or 1/2 size of the original is OK.) Method and Calculations: Provide sufficient information for another scientist/engineer to be able to reproduce your results Uncertainties - quantify random and systematic effects that contribute to your reported uncertainty. Hint: Report the Trial # first. You can trace rays by positioning the white horizontal line over the laser beam. To rotate the white lines, double-click and hold, and then drag to rotate the screenshot should include just the image of the mirror/lens with intersecting lines, not the whole browser window for your whole Desktop!!! BIU EEEE Score: 0/5 2. Repeat the process for ONE of the convex mirrors either trial 4 or 5. Find the focal length and radius of curvature. Describe the process you used to find the focal length. Use the same format: Summary: Trial number and focal length, with uncertainty (and units, of course!). Include a cropped screenshot of the still image from the video showing the intersecting rays. (Not too big! 600 x 400 pixels or 1/2 size of the original is OK.) Method and Calculations: Provide sufficient information for another scientist/engineer to be able to reproduce your results Uncertainties - quantify random and systematic effects that contribute to your reported uncertainty, Hint: 1-2 sentences per part. Don't forget units on all quantities! The screenshot should include just the image of the mirror/lens with intersecting lines, not the whole browser window for your whole Desktop!)
