Question

can someone help me with this activity

3. Spoons! Objective: Measure the radius of curvature of your flatware. Materials needed: • Stainless steel (or other shiny metal) spoon • Ruler Procedure: First, have some fun. Look at your reflection in the spoon, on the concave side and on the convex, from various distances. OK, ready to get serious now? Hold the spoon at arm's length, with the concave side towards you, and slowly bring it to your face. Note what happens to your reflection in the spoon. At a certain point, your reflection will disappear for a moment, then reappear. "Dial in" to this particular distance where your image doesn't form. You might need to hold the spoon directly in front of one open eye. Have a partner measure the distance from your eye to the spoon Record the results, and repeat the measurement a total of 6 times. Using the mirror equation, show that the distance at which the image disappears is the focal length of the mirror. Pretending, as usual, that the surface of your spoon is spherical, calculate its radius of curvature. Data/Analysis Trial Distance (cm) 1.200 cm 2.4/24cm 3.310 cm 4.3 70.com 5.199 cm 6.092cm Average: Just for fun Repeat the foregoing, using an actual concave mirror such as a cosmetic mirror.

Answer 1

Mirror equation to the is, one Image dissappear means. 5 otta uaf Image disappears focal length of at the a distance = mirror Here, Average distance at which the image disappears is - (0.250+ 0.4244 0310 +0.370 +0.199 +0.252) 0.301 cm A f= 0.301 cm - 0,301 cm 0. GO2 cm . Radius is of cuinadure = 0.602 cm. of the spoon.
