632.8 nm (wavelength of red light from a helium-neon laser) Given the wavelength, λ, of a photon, the energy, E, can be calculated using the equation: E=hcλ where h is Planck's constant (h=6.626×10−34J⋅s) and c the speed of light (c=2.998×108m/s).A calculator that can format a number to have as many significant figures as desired using proper scientific rounding rules. When adding values together, your result is only as significant as your value with the least significant decimal in the highest place.Significant figures, or sig figs for short, are the meaningful digits in a number. Often, leading zeroes or trailing zeroes can be removed and the number remains just as accurate (004 means the same as 4, for example). When removing digits, you must be able to identify the significant figures in order to retain...Calculate its speed in miles per hour (miles/h). We're in the know.
