5. a) With the aid of a clearly labeled diagram, describe an apparatus that can minimize heat lose and heat gain through Conduction, Convection and Radiation

Your target variable is δf, the magnitude of the difference in frequency between the waves emitted from the sonar device and the waves received by the device after reflecting off the whale. write an expression for δf in terms of the relevant frequencies using the subscript notation introduced above.

What are similarities and differences between refraction, reflection, diffraction and absorption?

Identify the theory that can be used to explain each phenomenon. answers diffraction: wave theory interference: wave theory reflection: both particle and wave theories refraction: both particle and wave theories
