Wave Interactions Waves that meet each other or an object in the environment may interact. There are several types of interactions that waves may have. Reflection occurs when a wave bounces back after striking a barrier. Reflected sound waves are called echoes; reflected light waves allow us to see objects. Refraction is the bending of a wave as it passes at an angle from one medium to another. One common example of refraction of light waves is the broken pencil effect that can be observed when a

coughs affect the respiratory rate. Pulse rate: Normal pulse rates limits: pulse rate is measured at beats per minute. To check for normal pulse rate it is measured while resting to get an accurate reading. The normal pulse rate in an adult is 60-80 beats per minute. Factors affecting pulse rates – raising or lowering: Pulse rate varies from minute to minute due to many factors. Exercise‚ fever stress‚ weight‚ temperature and medication affect the pulse rate. Other factors such as smoking and

Radar has been employed on the ground‚ in air‚ on the sea and in space. Radar finds a number of applications such as in airport traffic control‚ military purposes‚ coastal navigation‚ meteorology and mapping etc. The development of the radar technology took place during

Four medical cases that involve patients with bronchitis have been studied between the periods of 1866-1904. These cases can give an historian a large amount of information that can be used to understand more about the past. They give information surrounding the changes in treatment of bronchitis. They also give information about society such a class‚ religion and living conditions. Although‚ historians face challenges when trying to interpret old medical records‚ these can be overcome with perseverance
