STANDING WAVES A string attached to a turning fork is set vibrating at the same frequency as the tuning fork. The length and tension in the string are adjusted until standing waves are observed on the string. By knowing the tension in the string and the wavelength of the standing waves‚ the frequency of oscillation of the string and thus‚ the tuning fork is found. This value is then compared to a strobelight determination of the frequency. THEORY If transverse waves of constant

Heat Waves What is heat wave? A heat wave is a prolonged period of excessively hot weather‚ which may be accompanied by high humidity. While definitions vary‚ a heat wave is measured relative to the usual weather in the area and relative to normal temperatures for the season. Temperatures that people from a hotter climate consider normal can be termed a heat wave in a cooler area if they are outside the normal climate pattern for that area. What are the symptoms of heat strokes and sunstroke

The art of wave riding (‘he’enalu’‚ in old Hawaiian) was practiced in many coastal locations around the tropics among Pacific Islanders. "He’e" means to go from a solid to a liquid and "nalu" means surfing motion of a wave. This stand-up pastime of surfing came to its climax in Hawaii not only because of its coast having warm water and constant waves but Hawaiians are innately ocean people. Traditionally surfing prowess gained you social rank and power politically in the village. Commoners could

Although the number of waves per larva was different‚ it was higher than the waves produced in Table 2‚ the ChR2+ group. Larvae from this plate contracted immediately when the light was turned on and only produced waves during the interval the light was not on. Because the light flashed a set amount of times per second‚ the larva was not able to complete a full wave. This became more evident as the light continued to flash in a shorter time interval as the number of waves decreased as the MRR increased
