Question
Please Help!! I only have 10 minutes to complete this homework! Its a timed physics lab homework! I am just finding out its timed and im not really good with timed assigments! I started on it and hopefully we end up with the same answers and for the questinos I dont get to you can help me with. I am willing to give away a lot of points for this! help! quick! thank you!
Optics 1: A light ray has an incident angle of theta i = 38.2 degree going from Diamond (ni = 2.42) into Glycerin (nr = 1.47). Because the incident angle is greater than the critical angle total internal reflection occurs. What happens if the Glycerin is replaced with Glass (nr = 1.52)? Assume that the incident angle stays the same. 5. A The incident ray will pass through the boundary without refracting. B Total internal reflection does not occur and the light ray will refract with an angle of 22.9 degree. C Total internal reflection does not occur and the light ray will refract with an angle of 79.9 degree D Total internal reflection still occurs and the angle of reflection is 38.2. Optics 1: A converging lens has a focal length of f = 96.0 cm type of image is produced? 4. A Real B lconic C Holographic D Virtual Optics 1: An object is placed in front of a converging lens with the object distance being greater than the focal length. What can you say about the image? 3. A The image is virtual and upright. B The image is real and upright. C The image is virtual and inverted. D The image is real and inverted. Optics 1: Which of the following is true for a plane mirror? 2. A All light rays reflecting from the mirror pass through the focal point. B it produces a real image. C It produces a virtual image. D The image may be larger or smaller than the object. Optics 1: 1: What happens if you place an object exactly at the focal point of a converging lens or mirror? 1. A The outgoing light rays will be parallel and no image will form. B An inverted real image will form. C An inverted virtual image will form. D The image will be magnified by a factor of 10.Explanation / Answer
1.
A) the outing light will be parallel and no image will form
-----------------------------------------
2.
c) it produces a virtual image
------------------------------------
3.
D. The image is real and inverted
-------------------------
4.
1/145 + 1/S' = 1/96
S' = 284 cm
A. Real
-----------------------------
5.
C) total internal reflection does not occur and the light ray refract with an anle of 79.9
