How do you calculate the energy of light that has a wavelength of 10 cm?

Answer 1

Levi Acosta

E = 1.992 x #10^-24# Joules

E = #(h*c)/ lambda#

The Plank's Constant is represented by h, energy by E, and speed of light by c.

h = 6.64 x #10^-34# #m^2# kg /sec c = 300000 km/ sec #lambda# = 10 cm = 10/100 = 0.1 m

E = (6.64 x #10^-34# x 300000000)/ 0.1

E = 1.992 x #10^-24# Joules

Light energy can be found with the following formula: (E = \frac{hc}{\lambda}), where (E) is the light's energy, (h) is Planck's constant ((6.62607015 \times 10^{-34}) J·s), (c) is the light's speed ((2.998 \times 10^8) m/s), and (\lambda) is the light's wavelength in meters. Before entering the wavelength value into the formula, convert it from centimeters to meters (1 cm = 0.01 m).

When evaluating a one-sided limit, you need to be careful when a quantity is approaching zero since its sign is different depending on which way it is approaching zero from. Let us look at some examples.
