Light of wavelength 675 nm passes
through a double slit, and makes its
first minimum (m = 1) at an angle of
0.111 deg. What is the separation of
the slits, d, IN MILLIMETERS?
(Remember, milli means 10-3.)
(Unit = mm)

The california mussel (mytilus californianus) attaches itself to a rock or other solid surface with a bundle of filaments known as the byssus. imagine that 15.0 j of work is done to stretch the distal end of the byssus. it releases 10.8 j of thermal energy as it relaxes. what is the resilience of the distal end of the byssus?
