Knuckles creates a light ball from his fist impact.
Angsize formula = 2atan(tan(70deg/2)*[object length/panel height])
Solving for distance to the moon's middle from the screen = 2atan(tan(70deg/2)*[858/753]) = 77.16895470951 degrees
Moon diameter = 3,474,800 meters
http://www.1728.org/angsize.htm
Solving for distance, size is 3,474,800 and angle is 77.16895470951, distance is 2.1776E6 meters
Moon radius = 1,737,400 meters
Distance to the screen from the moon's frontal surface to the camera is therefore = 2.1776E6 - 1,737,400 = 440200 meters
Solving for the size of the light ball now:
2atan(tan(70deg/2)*[26/753]) = 2.76995799187333 degrees
http://www.1728.org/angsize.htm
Solving for size; distance is 440200 meters and angle is 2.76995799187333, size is 2.1286E4 meters
The diameter of the light ball is therefore 2.1286E4 meters, the radius of the light ball is therefore 10,643 meters.
F = L / 4 * pi * d ^ 2, where:
F (measured in watts / m ^ 2) = energy / radiant flux;
L = luminosity (measured in watts);
d = distance (measured in meters);
So. To find F, we need to guess what the lux is.
Lux (from Latin lux - light; Russian designation: lx, international designation: lx) is a unit for measuring illumination in the International System of Units (SI) [1]. Lux is equal to the illumination of a 1 m² surface with a luminous flux of radiation incident on it equal to 1 lm. Accordingly, the following will be fulfilled: 1 lux = 1 lm / m^2.
The wiki article (https://ru.wikipedia.org/wiki/Lux) indicates in the table that 32-130k suites = a clear sunny day. I will assume 81k suites.
But these are suites, and we need watts per square meter. To translate suites into this, we must multiply suites by 0.0079.
81,000 × 0.0079 = 639.9 W / m ^ 2.
Now d. The distance here is the distance of 10,643 meters
F = L / 4 * pi * d ^ 2
639.9 = L / (4 * 3.14 * (10643^ 2))
L = (4 * 3.14 * (10643^ 2)) * 639.9 = 9.10395021E11 joules/second
Light flash lasted roughly more than a full second so this would be equivalent to 217.58963217017 Tons of TNT
