Answer:
4.59 × 10⁻³⁶ kJ/photon
Explanation:
Step 1: Given and required data
- Wavelength of the violet light (λ): 433 nm
- Planck's constant (h): 6.63 × 10⁻³⁴ J.s
- Speed of light (c): 3.00 × 10⁸ m/s
Step 2: Convert "λ" to meters
We will use the conversion factor 1 m = 10⁹ nm.
433 nm × 1 m/10⁹ nm = 4.33 × 10⁷ m
Step 3: Calculate the energy (E) of the photon
We will use the Planck-Einstein's relation.
E = h × c/λ
E = 6.63 × 10⁻³⁴ J.s × (3.00 × 10⁸ m/s)/4.33 × 10⁷ m
E = 4.59 × 10⁻³³ J = 4.59 × 10⁻³⁶ kJ
Faster molecules have fewer collisions than slower molecules is True about molecular speed.
<h3>What is Molecular speed?</h3>
Molecular speed refers to the average distance gases or molecules travelled atca particular time rate.
It is valid in ideal gas, where the molecules do not interact with others.
Average molecular speed = Square root (3 (ideal gas constant) * (Temperature)/m)
Therefore, Faster molecules have fewer collisions than slower molecules is True about molecular speed.

They're only found in the nucleus and play an important role in keeping the atom stable because they carry a negative charge to counteract the proton's positive charge.
