Question

1) A single bi-convex lens (a lens with two convex surfaces) made of fused quartz (index of refraction n = 1.46) has surfaces with radii of curvature r₁ = 17.0 cm and r₂ = -17.0 cm. What is the focal length of the lens in air?

Tries 0/12

2) If an object is placed at p = 36.4 cm from the lens, where is the image? (Use plus sign for a real image, and minus sign for a virtual image.)

3) If the object has a height of h = 3.10 cm, how large is the image? (Use plus sign for an upright image, and minus sign for an inverted image.)

Answer 1

r=17cm, r = - 17cm, n = 1.46 = (*+1) CT b. § = 6146-1) (sem stocm) If = 18- 5cm 2) to - š = (W2 - 36.4 cm) ISIS -36.4 = on this story =T4=+3706 com m= e = h v=4 37.6 cm 3) ; ho = 3:1cm hit Bolcm x 37.6 cm - 36.4 cm | - - = - 3 2 • - 3.2 cm
