An interference pattern is seen on a screen after light passes through a single-slit slide. Bright fringes are seen when the path difference between the upper-most and lower-most rays multiples of this.
What is half the wavelength of the light?
100
This is seen when a high frequency photon and an electron collide in space.
What is the photon moves to a lower frequency and gives the electron energy/momentum. Bonus: what is this phenomenon called?
200
When analyzing projectile motion, you usually need to analyze motion in this dimension first.
What is vertical. Bonus: what is the formula for initial vertical velocity?
200
This is the name of the phenomenon that causes a canoe to move backward if you take a step forward.
What is recoil?
200
A proton travels due east through a magnetic field pointing due north. This is the direction of the magnetic force felt by the proton.
What is up? Bonus: what would be the direction of the force felt by an electron?

Compared to the interference pattern formed by a double slit, a diffraction grating's pattern looks like this.
What is widely spaced, narrow bright fringes?
200
The hadron uu is impossible for this reason.
