What is the energy of green light with a wavelength of 5.50x10^-7m?
use
E=hc/lambda
where h= Planck's constant
To calculate the energy of green light with a wavelength of 5.50x10^-7m, you can use the equation E = hc/λ, where E represents the energy of the light, h is Planck's constant (6.626 x 10^-34 J·s), c is the speed of light (3.00 x 10^8 m/s), and λ is the wavelength.
First, substitute the values into the equation:
E = (6.626 x 10^-34 J·s) * (3.00 x 10^8 m/s) / (5.50 x 10^-7m)
Next, perform the multiplication and division:
E = 1.08 x 10^-19 J
Therefore, the energy of green light with a wavelength of 5.50x10^-7m is approximately 1.08 x 10^-19 Joules.
To calculate the energy of a specific wavelength of light, you can use the equation:
E = hc/λ
where E is the energy of the light, h is Planck's constant (6.62607015 × 10^-34 J·s), c is the speed of light (2.998 × 10^8 m/s), and λ is the wavelength of light.
Let's plug in the values:
λ = 5.50 × 10^-7 m
h = 6.62607015 × 10^-34 J·s
c = 2.998 × 10^8 m/s
Now we can calculate the energy:
E = (6.62607015 × 10^-34 J·s * 2.998 × 10^8 m/s ) / (5.50 × 10^-7 m)
E = 3.617 × 10^-19 J
Therefore, the energy of green light with a wavelength of 5.50x10^-7m is approximately 3.617 × 10^-19 J.
