One of the reasons that quantum mechanics can seem so shocking is that quantum behavior is not readily apparent in our everyday life. as an example, assume that you are a particle of mass 65 kg. according to planck, you should have an associated wavelength. but you don't really seem to act like a wave: for example, you can pass through a doorway without diffracting. to explore whether this contradicts quantum mechanics, consider the doorway to be 1 m wide, and also consider that diffraction effects are only substantial when the wavelength is at least comparable to the width of the opening. given this, what is the largest speed at which you could pass through the doorway and experience diffraction?

Pl asaaap ! match the term to the correct description. a type of wave that transfers energy where the particles in the medium move perpendicular to the direction in which the energy is traveling. a type of wave that transfers energy where the particles in the medium move parallel to the direction in which the energy is traveling. movement that is back and forth, like an equal sign = a type of wave that transfers energy where the particles in the medium move in a circle motion while the energy travels left or right. movement that is like a t transfers energy from one location to another 1. wave 2. parallel movement 3. perpendicular movement 4. transverse wave 5. longitudinal wave 6. surface wave

Light from a sodium lamp passes through a diffraction grating that has 1000 slits per millimeter. the interference pattern is viewed on a screen 1.000 m behind the grating. the first (m = 1) two bright yellow fringes that are visible are 0.7288 m and 0.7300 m from the central maximum. what are the wavelengths of these two fringes?
