Using electromagnetic waves, you generally cannot resolve any structures that are smaller than the wavelength you are using. CD, DVD, and Blu-ray players use small "pits" that encode the 0s and 1s of the digital information stored on them-the smaller the pits, the more information you can store. A DVD can store 4. 7 GB, and a Blu-ray can store \(25 \mathrm{~GB}\). If a DVD player typically uses lasers that emit red light in the wavelength range from \(640 \mathrm{~nm}\) to \(660 \mathrm{~nm}\), what do you expect the wavelength and color of a Blu-ray laser to be?
