Christian Huygens in the 1600’s invented the first clock which was small enough to fit in an ordinary room but much more accurate than the large tower clocks of his day. What was his big idea? Why does it work well on land but not at sea? (Ships would have to wait many years for an accurate on-board timepiece).

how would you solve this? Light is emitted from the light source, reflects from mirror surface X to the plane mirror, and then to the position of surface Z. By the time the light moves from the X to Z position, mirror surface X will have moved to the position of mirror surface Z. The light then continues to the observer. The distances from the light source and the observer to the rotating mirrors are negligible. The distance from the rotating mirrors to the plane mirror is 35.0 km.If the mirrors are rotating at 480 rev/s, the speed of light calculated from the given information is a 7.44 10–9 m/s b 1.34 108 m/s c 2.98 10–8 m/s d 3.36 107 m/s

Biologists use optical tweezers to manipulate micron-sized objects using a beam of light. In this technique, a laser beam is focused to a very small-diameter spot. Because small particles are attracted to regions of high light intensity, the focused beam can be used to “grab” onto particles and manipulate them for various experiments. In one experiment, a 10 mW laser beam is focused to a spot that has a diameter of 0.62 μm.a. What is the intensity of the light in this spot?b. What is the amplitude of the electric field?
The sonar unit on a boat is designed to measure the depth of fresh water (p = 1.00 x 103 kg/m³, Bad = 2.20 x 109 Pa). When the boat moves into salt water (p = 1025 kg/m³, Bad = 2.37 x 109 Pa), the sonar unit is no longer calibrated properly. In salt water, the sonar unit indicates the water depth to be 8.87 m. What is the actual depth (in m) of the water? Number i ! Units m
