Bohr’s model indicates that this is the right relationship. An electron’s orbital radius grows in direct proportion to the square of its principal quantum number (n²). The orbit’s radius grows quickly as the quantum number rises. Because the centripetal and electrostatic forces balance at various radii for every energy level, this quadratic relationship results.

High-speed electrons or positrons released from the nucleus during beta decay are known as beta rays. The de Broglie wavelength is a distinctive wavelength linked to the motion of these electrons or positrons.

When waves bend around an obstruction and interfere with one another, this phenomenon is known as diffraction. The wavelength of beta rays can be ascertained by analyzing the diffraction pattern that results from their diffractive action through a crystal lattice.

Option D is the right response since diffraction is how beta ray wavelength is determined.

The radiation energy divided by mass, or 10/2 = 5 J/kg in this instance, is the absorbed dose of radiation.

Since 1 J/kg is = 100 rad, thus 5 J/kg = 500 rad.

The rate at which flux changes per unit of time is known as the induced Emf.

emf is equal to ∆Ø/∆t.

When the amount of flux flowing through the coil in a given amount of time doubles,

E’ = 2(∆Ø/∆t).

E’ = 2E.

The emf doubles if the flux is “doubled” because E is directly proportional to the flux change.

The speed of light is equal to the photon velocity. Although photons have no mass, their energy is E = hf = hc/λ. Planck’s constant is h = 6.626*10-34 Js in this case. The electromagnetic wave’s wavelength and photon energy are inversely correlated.

E=6.626×10−34 × 3×108​/1240×10-9 ≈ 1.00 eV.

The SI unit for resistance is ohm.

The SI unit for current is the ampere.

The SI unit for power is watts.

The SI unit of electric potential difference is volts.

The input voltage will be equal to the number of pulses per second in a rectified voltage. Since the input voltage is 50 Hz, there are 50 pulses per second.

In a vacuum, photons travel faster than in liquid water.

Photons move at the speed of light, or roughly 299,792,458 meters per second (186,282 miles per second), in a vacuum, like space.

However, because of interactions between the photons and the medium’s atoms or molecules, light moves a little more slowly in a material medium, such as liquid water, than it does in a vacuum. Light travels at about 225,000,000 meters per second in water, which is roughly 3/4 of its speed in a vacuum.

The medium’s refractive index, which measures how much light is slowed down when it travels through a substance as opposed to a vacuum, is the cause of this speed differential.
