Coherent light from a sodium-vapor lamp is passed through a filter that blocks everything except for light of a single wavelength. It then falls on two slits separated by 0.510 {\rm mm}. In the resulting interference pattern on a screen 2.30 {\rm m} away, adjacent bright fringes are separated by 2.70 {\rm mm}. What is the wavelength of the light that falls on the slits?

Complete the statement about memory improvement. ( )involves organizing and breaking down information into easier groups to expand capacity. rehearsal is the verbal repetition of information. these techniques are especially important for the improvement of ( ) memory.

Acalorimeter uses the principle that thermal energy flows from hotter material to colder material until both reach the same
