Answer:
462 nm
Explanation:
Given: width of the slit, d = 5.6 × 10⁻⁴ m
Distance of the screen, D = 4.0 m
Fringe width, β = 3.3 mm = 3.3 × 10⁻³ m
First dark fringe means n =1
Wavelength of the light, λ = ?

The value of 1 is 10 million. The place value would be 10,000,000.
Hope I helped.
The amount of work done by the student in carrying the backpack is 30.6 J
<h3>Definition of workdone </h3>
Workdone is defined as the product of force and distance moved in the direction of the force.
Work done (Wd) = Force (F) × distance (d)
Wd = Fd
Also,
Force (F) = mass (m) × acceleration (a)
F = ma
Therefore,
Wd = (ma) × d
With the above formula, we can obtain the work done by the student.
<h3>How to determine the Workdone </h3>
From the question given above, the following data were obtained:
- Mass (m) = 12 Kg
- Acceleration (a) = 0.51 m/s²
- Distance (d) = 5 m
- Workdone (Wd) =?
Wd = (ma) × d
Wd = 12 × 0.51 × 5
Wd = 30.6 J
