During a baseball game, a baseball is struck at ground level by a batter. The ball leaves the baseball bat with an initial speed
v0 = 28 m/s at an angle θ = 21° above horizontal. Let the origin of the Cartesian coordinate system be the ball's position the instant it leaves the bat. Air resistance may be ignored throughout this problem.

Answer:
Explanation:
Given;
Thickness of the glass plate,
refractive index of the glass plate,
wavelength of light source in vacuum,
distance between the source and the screen,
Distance travelled by the light from source to screen in vacuum:
So the no. of wavelengths in the vacuum:
.......................(1)
<u>Now we find the wavelength of the light wave in the glass:</u>
where:
wavelength of light in the medium of glass.
Now the no. of wavelengths in the glass:
............................(2)
From (1) & (2):
- total no. of wavelengths are there between the source and the screen:
