For electrons moving at speeds close to c, the speed of light, the expression for the de Broglie wavelength (eqn 7A.11, 1= h/p) needs to be corrected for relativistic effects: h 2m eAq 1+ 2m.c where c is the speed of light in vacuum and Aø is the potential difference through which the electrons are accelerated.

Answer the following questions about a Blu-ray laser:(a) The laser on a Blu-ray player has a wavelength of 405 nm. In what region of the electromagnetic spectrum is this radiation? What is its frequency? (b) A Blu-ray laser has a power of 5 milliwatts (1 watt = 1 J s−1). How many photons of light are produced by the laser in 1 hour? (c) The ideal resolution of a player using a laser (such as a Blu-ray player), which determines how close together data can be stored on a compact disk, is determined using the following formula: Resolution = 0.60(λ/NA), where λis the wavelength of the laser and NA is the numerical aperture. Numerical aperture is a measure of the size of the spot of light on the disk; the larger the NA, the smaller the spot. In a typical Blu-ray system, NA = 0.95.
