The energy of the photon from the calculation performed is 3.5 * 10^-16 J.
<h3>What is a photon?</h3>
A photon is a packet of light. It was derived from the theory of Albert Einstein. The energy of a photon is obtained from; E = hc/λ
- h= Plank's constant
- c = speed of light
- λ = wavelength
Now we have that;
E = 6.6 * 10^-34 * 3 * 10^8/562 * 10^-9
E = 3.5 * 10^-16 J

Time taken for star to reach Earth = 7.5 years
<h3>Further explanation</h3>
Given
7.5 light years(distance Earth-star)
Required
Time taken
Solution
Speed of light=v = 3 x 10⁸ m/s
1 light years = 9.461 × 10¹⁵ m= distance(d)
So time taken for 1 light years :
time(t) = distance(d) : speed(v)
t = 9.461 × 10¹⁵ m : 3 x 10⁸ m/s
t = 3.154 x 10⁷ s = 1 years
So for 7.5 light years, time taken = 7.5 years
