Chemical bonds are broken to supply us with energy. Without bonds, and our ability to break them, the food we eat would not supply us with energy.
The wavelength of a photon that has an energy of E = 3.69×10−19 J is 5.42 x 10⁻⁷ m.
<h3>What do you mean by wavelength?</h3>
The space between corresponding points (adjacent crests) in adjacent cycles is known as the wavelength () of a waveform signal that is sent in space or down a wire.
The wavelength can be calculated by the given formula
E = hc/λ
Where, E is energy = 3.65 x 10⁻¹⁹ J
h is plank's constant = 6.626 x 10⁻³⁴ J.sec
c is speed of light = 2.9 × 10⁸ m/s
Putting the values in the formula
λ = (6.626 x 10⁻³⁴)(2.9 × 10⁸) / (3.65 x 10⁻¹⁹) = 5.42 x 10⁻⁷ m.
Thus, the wavelength, λ is 5.42 x 10⁻⁷ m.
