Answer:
wavelength: the distance between successive crests of a wave
frequency: the rate per second of a vibration constituting a wave, either in a material (as in sound waves), or in an electromagnetic field (as in radio waves and light)
electromagnetic energy is used for wifi, cell phones, microwave ovens etc.
the electromagnetic spectrum includes radio waves, microwaves, infrared radiation, visisble light, ultraviolet, xrays and gamma rays
the only part we can see is visible light
visible light can be characterised by the colours of the rainbow
the longest wavelength is red and the shortest is violet
when combined, the colour is perceived as white or beige
Answer:
Injury to the alveolar-capillary membrane
Increased alveolar-capillary permeability
Decreased lung compliance
Explanation:
Acute respiratory distress syndrome (ARDS) is a serious health problem that affects the lungs, which is caused by significative amounts of fluid that fill the air sacs. ARDS may be caused by distinct conditions such as, for example, pneumonia, sepsis, and traumatic injury. ARDS is a type of respiratory failure that results in decreased oxygen levels and increased carbon dioxide (CO2) concentration into the bloodstream.
