Answer:
We can retain the original diffraction pattern if we change the slit width to d) 2d.
Explanation:
The diffraction pattern of a single slit has a bright central maximum and dimmer maxima on either side. We will retain the original diffraction pattern on a screen if the relative spacing of the minimum or maximum of intensity remains the same when changing the wavelength and the slit width simultaneously.
Using the following parameters: <em>y</em> for the distance from the center of the bright maximum to a place of minimum intensity, <em>m</em> for the order of the minimum, <em>λ </em>for the wavelength, <em>D </em>for the distance from the slit to the screen where we see the pattern and <em>d </em>for the slit width. The distance from the center to a minimum of intensity can be calculated with:
From the above expression we see that if we replace the blue light of wavelength λ by red light of wavelength 2λ in order to retain the original diffraction pattern we need to change the slit width to 2d:

Answer:
1.60 g
Explanation:
From the attached file below:
we can deduce that:
The distance traveled by 2 s will be:
x = vt
x = 20 m/s × 2 s
x = 40 m
The length is quarter of the circle with radius r,
so; if 2 πr = 4 x
Then radius (r) will be:
r = 25.5 m
The centripetal acceleration can be expressed as:
so;
a = 15.7 m/s²
the magnitude of the acceleration experienced by your unfortunate passengers in terms of acceleration due to gravity is then determined by the equation:
∴ The magnitude of the acceleration experienced by your unfortunate passengers during the turn = 1.60 g
