When waves approach an irregular shoreline, do the waves refract (bend) towards the parts of the coastline that stick out (headlands/shallower water)? Or do the waves refract (bend) towards the parts of the coastline that are recessed (bays/deeper water)? choose one Waves do not refract (bend) along irregular shorelines. Waves refract (bend) toward bays/deeper water Actually wave refraction (bending) depends on water temperature - not water depth. Waves refract (bend) toward headlands/shallower water.

The star 18 Scorpii's mass is 2.0 x 103 kg, its radius is 7.0 x 105 km, and it has a rotational period of approximately 23 days. If 18 Scorpii should collapse into a white dwarf of radius 5.8 x 103 km, what would its period (in s) be if no mass were ejected and a sphere of uniform density can model 18 Scorpii both before and after? 4E-4 X S

You have a telescope that consists of two converging lenses which are placed a distance apart which is approximately equal to the sum of their focal lengths. Focal length 1 is appriximatly 5.5cm and focal length 2 is approximatly 25cm. The lens closest to the onject should have a resonably long focal length and the eyepiece lens should have a relatively short focal length to get good magnification. a. draw a scale ray diagram for a telescope using one long and one short focal length lens. b. Estimate how much larger your distance object appears through your telescope and then calculate the angular magnification.
