What difficulties does the uncertainty principle cause in trying to pick up an electron with a pair of forceps? Does the uncertainty principle apply to nature itself or only to the results of experiments? That is, is it the posi- tion and momentum that are really uncertain, or merely our knowledge of them? What is the difference between these two interpretations?

The particle model of light requires some or all of the following assumptions: 1) The particles are small in size compared to the spacing between them. II) The particles have very small mass. III) The particles are travelling very quickly. A beam of red light is observed to pass through a beam of blue light. In order to explain this observation, which of the above assumptions is/are required? (a) I only (b) III only (c) I and II only (d) I and III only (e) I, II and III Which one of the following properties of a wave decreases as the wave moves along a spring? (a) amplitude (b) wavelength (c) speed (d) frequency (e) period A source S generates circular waves on a lake. The pattern of wave crests is shown in the diagram below.
