Question

Please help! Is there another way that 3.40x10^-19J can be imputed on a computer. I have the right answer but it is wrong.

An element emits light at a wavelength of 584 nm. What is the energy of the photon with that wavelength?

Write your answer in scientific notation with the appropriate significant figures and unit. The exponent of 10 is written with the carat (^) symbol, so 10^n.

Answer 1

The energy of the photon with the wavelength of 584 nm is 3.4×10¯¹⁹ J

How to determine the frequency of the photon

• Wavelength (λ) = 584 nm = 584×10⁻⁹ m
• Speed of light (v) = 3×10⁸ m/s
• Frequency (f) = ?

f = v / λ

f = 3×10⁸ / 584×10⁻⁹

f = 5.14×10¹⁴ Hz

How to determine the energy

• Planck's constant (h) = 6.626×10¯³⁴ Js
• Frequency (f) = 5.14×10¹⁴ Hz
• Energy (E) =?

E = hf

E = 6.626×10¯³⁴ × 5.14×10¹⁴ Hz

E = 3.4×10¯¹⁹ J
