The yellow light from a helium discharge tube has a wavelength of 587.5 nm. When this light shines on a certain diffraction grating, it produces a first-order principal maximum (m = 1) at an angle of 1.250°. Calculate the slit spacing for this grating.

Can somebody explain to me how newton's 3rd law relates to momentum? ~ap physics 1

Spend time observing or thinking about events that involve matter and energy. which events can you explain? which events can’t you explain?

Acoil formed by wrapping 80 turns of wire in the shape of a square is positioned in a magnetic field so that the normal to the plane of the coil makes an angle of 28.0° with the direction of the field. when the magnetic field is increased uniformly from 200 µt to 600 µt in 0.400 as, an emf of magnitude 80.0 mv is induced in the coil. what is the total length of the wire?
