Classical physics is a good approximation to modern physics under certain circumstances. What are they?
Prescriptions for vision correction are given in units called dioptres (D). Determine the meaning of that unit. Obtain information (perhaps by calling an optometrist or performing an internet search) on the minimum uncertainty with which corrections in dioptres are determined and the accuracy with which corrective lenses can be produced. Discuss the sources of uncertainties in both the prescription and accuracy in the manufacture of lenses.
Models are particularly useful in relativity and quantum mechanics, where conditions are outside those normally encountered by humans. What is a model?
How does a model differ from a theory?
Diffraction spreading for a flashlight is insignificant compared with other limitations in its optics, such as spherical aberrations in its mirror. To show this, calculate the minimum angular spreading of a flashlight beam that is originally \(5.00\,{\rm{cm}}\) in diameter with an average wavelength of \(600\,{\rm{nm}}\).
