The orange color of a neon lamp results from an electric current being passed through a tube filled with neon gas.  If this light passes through a prism, the light divides into distinct “lines” of colored light.  This pattern is called the light spectra of neon.

A green laser emits light with a wavelength of 532 nm. Calculate: The energy of a single photon; E=hcλE = \frac{hc}{\lambda}  in joules. The frequency of this light;  v=cλv = \frac{c}{\lambda}. Constants: h=6.626×10−34 J/Hz c=3.00×108 m/sc = 3.00 \times 10^8 \, \text{m/s} 1Hz = 1s-1 = 1/s   Show your work and answer in the space provided. Make sure to include units during your calculations. Answer should have correct units and be in correct significant figures.
