The equation for photon energy, e, is e=hcλ where h = 6.626×10−34 j⋅s (planck's constant) and c = 2.99×108 m/s (the speed of light). what is the wavelength, λ, of a photon that has an energy of e = 4.52×10−19 j ? express your answer numerically in meters.

Ans. : frostbite is when exposure to cold temperatures causes freezing to the skin or other tissues. it most commonly affects the hands, feet, and face. the longer areas are exposed to cold, typically the worse the frostbite. the water temperature used for rewarming a frostbitten part should be : (102 -105) f degrees.
