<u>Answer</u>:
Speed = 3.33 m/s
<u>Explanation</u>:
Formula:
Speed = distance / time
<em>Here distance is 800 metres and time is 240 seconds</em>
<em>Using the formula:</em>
Speed = 800 / 240
Speed = 3.33 m/s
To solve this problem we will apply the concepts related to the double slit-experiment. Under this concept we understand the relationship between the minimum angle, depending on the order of the fringes, the wavelength and the distance between slits. Therefore we have the following relation,
Here,
m = Order of the fringes
D = Distance between slits
= Wavelength
Replacing with our values we have,
Through the relationship between distances then we have that the basic amplification distance is given by the relationship between the distance of the slit L and the angle, then
Thus the width of the central maximum is
Therefore the widht is 0.466m
