How much energy does a 930 nm wave of light have? (The speed of light in a vacuum is 3.00 x 108 m/s, and Planck's constant is 6.626 x 10-34 Jos.)
A. 1.85 x 10-31 J
B. 4.68 x 1018 j
C. 2.14 x 10-19 J
D. 4.21 x 1035 J

Explanation:

We have,

Wavelength of a light is 930 nm

It is required to find the energy of a wave of light. The energy of a wave is given in terms of following as :

So, the energy of the wave is

the food using pesticides in the future will harm you by giving you diseases like cancer or something since they have things that we should not eat in it like chemicals or pesticides. that is why organic food is more expensive because they take the time to make it right and healthy for you to eat.
