A lens is made from glass with an index of refraction of 1.66 for violet light and 1.61 for red light. Both sides of the lens are convex with equal radii of curvature. For which color, violet or red, is the focal length larger? Explain how you know.
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.)...
A certain thin lens is made of glass with refraction index ?lens=1.500. In air, where the index of refraction is 1.000, the lens has focal length ?0=15.5 cm. What is the focal length ? of the lens when immersed in water, where the index of refraction is 1.330?
A certain thin lens is made of glass with refraction index nlens = 1.500. In air, where the index of refraction is 1.000, the lens has focal length f0 = 26.5 cm. What is the focal length f of the lens when immersed in oil, where the index of refraction is 1.460?
A "biconvex" lens is one in which both surfaces of the lens bulge outwards. Suppose you had a biconvex lens with radii of curvature with magnitudes of |R1|=10cm and |R2|=15cm. The lens is made of glass with index of refraction nglass=1.5. We will employ the convention that R1 refers to the radius of curvature of the surface through which light will enter the lens, and R2 refers to the radius of curvature of the surface from which light will exit...
The thick lens shown at right is made from glass with index of refraction 1.50. The thick lens has thickness of 6.0 cm and radii of curvature of 8.00 cm and 10.00 cm. (a) Find the focal length of this thick lens in air and the position of its focal points (F and F) and its principal points (H, and H,) with respect to the front and back of the lens respectively. (b) Draw a sketch showing the locations of...
A meniscus lens is made with the radius of curvature of the convex surface being 45.0 cm and the concave surface 25.0 cm. If the glass used has index of refraction 1.50, what is the focal length of this lens?
