Question 1 Using the formula n=c/v and the values from table 1, which material has the highest density?
question 2
Based on what you have learned about light waves and density, which material would bend light more noticeably, water or diamond?

The bar of prob. 5/82 is repeated here. the ends of the 0.4-m bar remain in contact with their re- spective support surfaces. end b has a velocity of 0.5 m/s and an acceleration of 0.3 m/s2 in the di- rections shown. determine the angular accelera- tion of the bar and the acceleration of end a.

This is the number of complete movements of a wave per second.
