Which is the relationship between photon energy and the color of light?
1 answer:
The energy of a photon is given by
where
h is the Planck constant
f is the frequency of the light.
From this formula, we see that the higher the frequency, the greater the energy, and viceversa.
Now let's have a look at the frequencies of the different colors of visible light. Violet is the color with higher frequency, while red is the color with lower frequency. This means that violet photons have the greatest energy, while red photons have the least amount of energy. So, correct answer is
<span>C. Red photons have the least amount of energy.</span>

Answer:
v = (10 i ^ + 0j ^) m / s, a = (0i ^ - 9.8 j ^) m / s²
Explanation:
This is a missile throwing exercise.
On the x axis there is no acceleration so the velocity on the x axis is constant
v₀ₓ = 10 m / s
On the y-axis velocity is affected by the acceleration of gravity, let's use the equation
v_y = - g t
at the highest point of the trajectory the vertical speed must be zero
v_y = 0
therefore the velocity of the body is
v = (10 i ^ + 0j ^) m / s
the acceleration is
a = (0 i ^ - g j⁾
a = (0i ^ - 9.8 j ^) m / s²
