1) Concept Simulation 25.2 illustrates the concepts pertinent to this problem. A 1.70-cm-high object is situated 22.2 cm in front of a concave mirror that has a radius of curvature of 10.0 cm. Calculate (a) the location and (b) the height of the image.
(a) NUMBER: UNITS: (b) NUMBER: UNITS:
2) Two converging lenses have the same focal length of 5.00 cm. They have a common principal axis and are separated by 23.2 cm. An object is located 10.0 cm to the left of the left-hand lens. What is the image distance (relative to the lens on the right) of the final image produced by this two-lens system?
Final image distance = NUMBER: UNITS:
(The number of significant digits is set to 3; the tolerance is +/-1 in the 3rd significant digit )
3) Light travels at a speed of 2.066 × 108 m/s in a certain substance. What is the index of refraction of this substance? Use 2.998 × 108 m/s for the speed of light in a vacuum.
NUMBER: UNITS:
(The number of significant digits is set to 4; the tolerance is +/-1 in the 4th significant digit)
4) For light that originates within a liquid and strikes the liquid/air interface, the critical angle is 32°. What is Brewster's angle for this light? NUMBER: UNITS:
(The number of significant digits is set to 2; the tolerance is +/-1 in the 2nd significant digit)
