A beam of light travels in air and then passes through a piece of glass at an angle of 45 degrees to the normal. As the light passes from the air into the piece of glass, the light ray is bent, what is the angle of refraction measured from the normal?

Why is it a good idea to leave an interview being courteous and polite?

Assume the existence of a bankaccount class. define a derived class, savingsaccount that contains two instance variables: the first a double, named interestrate, and the second an integer named interesttype. the value of the interesttype variable can be 1 for simple interest and 2 for compound interest. there is also a constructor that accepts two parameters: a double that is used to initialize the interestrate variable, and a string that you may assume will contain either "simple", or "compound", and which should be used to initialize the interesttype variable appropriately. there should also be a pair of functions getinterestrate and getinteresttype that return the values of the corresponding data members (as double and int respectively).
