A 4.0 cm tall object is 5.0 cm in front of a diverging lens with a focal length of -6.0 cm. A converging lens with a focal length of 6.0 cm is located 8.0 cm behind the diverging lens. (As viewed from the side, from left to right, the sequence is object - diverging lens - converging lens - observer. Rays then travel from left to right through the system.) (a) Use ray tracing to draw image 1 and image...
A laser emitted a 0.1 ms long pulse of light with total energy 10 J. The average pressure of such a pulse focused on a spot of diameter 1mm on a fully reflective surface is: OA. 850 Pa B. 0.17 mN OC. 6.6 N/m2 D. None of the above The index of refraction of germanium is 5.5. The critical angle for total internal reflection, at germanium/air interface is about: A. 800 OB. 340 C. 60° D. None of the above...
Question 3 A 5-cm tall object is placed 15.4 cm in front of a diverging lens. If the focal length is 12.5 cm. the image is real, inverted, and reduced real, upright, and reduced virtual, upright and enlarged virtual, upright, and reduced
7. Consider a converging lens that has a focal length (f). Which one of these is correct about the image when the object is placed in front of the lens at a distance of (f/4 )? The image is real, erect, and diminished The image is real, erect, and magnified The image is virtual, inverted, and magnified The image is virtual, erect, and magnified The image is virtual, erect, and has the same size as the object The image is...
