Rates of energy expenditure during physical activity are commonly described as light, moderate, or vigorous intensity. Energy expenditure is expressed by multiples of the metabolic equivalent of task …

There are three levels of exercise intensity: low intensity, medium intensity, and high intensity. The intensity level of exercise determines your stage of exercise, and the amount of calories you burn …

The higher the heartbeat, the higher the intensity of exercise. For moderate exercise intensity, the intensity should be 65% to 75% of your maximum heart rate. Can you do the math calculations? For …

To understand the concept of sound intensity and how it is measured. To learn how to operate a Sound Level Meter

We define the intensity I as the rate at which energy E flows through a unit area A perpendicular to the direction of travel of the wave. Intensity = Power / Area

“spectrum” is a graph of an objects intensity as a function of wavelength. “Blackbody” is an object that is dense, absorbs all light that hits it, remits that light with a spectrum depends on the objects …

· Same energy flow at different wavelengths gives different visual response and thus different brightness. · LE is maximum for a light source emitting at 2 = 555 nm. · Quality => sodium lights for …
