Simon, a physics student, has an idea. He wants to build a device that will let him see around corners. He suggests that if he places a diffraction grating at a corner it would bend the light towards his eyes and he could see the light coming from around the corner. Using evidence from these videos, state why you think this would or would not be possible, and what the limitations of this are. Also, if he's going to place something at the corner anyway, would there be a better device to use than a diffraction grating

Isobars are lines of constant or equal pressure on a weather map. they can be used to find areas of low or high pressure over a broad area, and they can tell us how intense the system may be. on weather maps, you may have noticed areas that have a large l or h over a region with lines circling around them. the l stands for low pressure and h stands for high pressure. the lines circling them are isobars. check out the pressure system and isobars over georgia and florida. what is the present weather in this area ? a) clear and sunny b) cold and cloudy c) changing weather d) lots of precipitation
