Answer:
Y = 0.0254 m = 25.4 mm
Explanation:
The formula for the fringe spacing in Young's Double-slit experiment is given by the following formula:

where,
Y = fringe spacing = 0.0176 m
λ = wavelength = 425 nm = 4.25 x 10⁻⁷ m
L = Distance between screen and slits
d = slit separation
Therefore,

Now, for:
λ = 614 nm = 6.14 x 10⁻⁷ m

<u>Y = 0.0254 m = 25.4 mm</u>
It makes an echo and it circles around it.
The object is not accelerating. I think I got this question right
Answer:
44.8 m/s
Explanation:
Use the Initial Speed Formula:
InS = 2(d/t) - Final Speed
InS = 2(55/1,25) - 43.2
InS = 2.44 - 43,2
InS = 88 - 43,2
InS = 44.8 m/s
