When two gamma-ray photons with the same energy but moving in opposite directions interact, pair production can occur. Option C is therefore accurate.

From the longest to the shortest wavelengths, the electromagnetic spectrum consists of radio waves, microwaves, infrared, ultraviolet, X-rays, gamma rays, and optical/visible light.

According to Einstein’s equation E=mc^2, mass and energy are directly proportional. It asserts that an object’s energy (E) is directly proportional to its mass (m) times the square of the speed of light (c^2). According to this equation, nuclear reactions demonstrate that a small amount of mass can be transformed into a significant amount of energy.

The positron was discovered by accident as a result of Carl D. Anderson’s experiment on cosmic rays. Anderson opened a lead plate and a cloud chamber to cosmic rays. This device was surrounded by a magnet, which caused the particles to bend in various directions according to their electric charge. Each positron’s ion trail showed up on the photographic plate with a curvature that matched an electron’s mass-to-charge ratio, but in a direction that indicated the charge was positive. It was anti-matter’s first proof.

3 MeV = 3 x 106 eV is the photon’s energy (E).

The photon’s linear momentum is p = E/c, where c is the vacuum speed of light.

P is therefore equal to (3 x 106)/(3 x 108), or “0.01 eV s m.”-1.

Given that both have the same dimensions, it is a fact that Planck’s constant and angular momentum are comparable.

E = hv

where the frequency dimensions are the inverse of the time period, or T−1, and the energy dimensions, E, are ML2T−2.

Therefore, ML2T−2=[h]T−1

or [h]=ML2T−1

Angular momentum, L=Iω, now

where radian is dimensionless and omega units are the inverse of time (rad/sec).

Since I is of the form kMx2, its units are ML2.

Consequently, [L]=ML2T−1; T-1 due to rad/sec, which would leave T-1 since radians don’t have dimensions.

The following is the explanation:

l = 1500 W/m^2.

λ = 5000Å

E = hf

E = hc/λ

Since c is equal to 3×10^8 (the speed of light),

Plank’s constant, h, is equal to 6.626 × 10^-34 m^2 kg / s.

Photon count received (n = I/E)

Iλ/hc = n

n = (1500)(5000Å)/(6.626 × 10^-34 )(3×10^8) n = 3.77×10^21

Seven-segment Together, the displays can show the numbers 0 through 9 as well as a few other numbers. These days, using a calculator to display numbers is very simple.
