![]() ![]() The goal of this video is to show players and coaches visually how to be more intense in hockey – the NHL intensity formula – so that players can be clear on what they need to do when someone tells them they need to be more intense. But it is not clearly linked to any specific mechanic or action. Intensity is a common word used in hockey. This means selecting short and easy to understand visual terms linked to specific mechanics and actions. Accurate verbiage, to borrow a common (and slightly sarcastic) phrase. In order to do this, we need to use the right words. At Train 2.0 our goal is to give players clear instructions that lead to in game results. So players will often hear these terms but never act on them because they simply aren’t sure what to do. But for younger players from junior to minor hockey these instructions are often not clear. Experienced players likely have an idea what this means. Intensity does not depend on the ‘amount of energy’ transported but it depends on the ‘rate of energy’ per unit time and area (more related to the speed of transport of energy).Coaches often tell their players to ‘be more intense’ or ‘battle’ or ‘compete’.The minimum intensity of sound that a human can hear is 10 -12Wm -2 and the maximum is 1 Wm -2.When there is a point source used without directing the light or sound in a direction, the area of a sphere = 4πr 2 is used instead of the area of circle for calculating intensity.While using the Intensity formula, remember that the area is measured in the ‘ plane’ perpendicular to the direction of the propagation of energy.It is important to note that light and sound does not travel in a circular form from the source, instead it travels in a spherical form.This in return increases the intensity of the sound wave. The more the wave displaces the particles, the more it will be able to move efficiently through the medium. Δs is the displacement amplitude of particles in a medium. It is understood that fast travelling waves impart more energy thus more intensity. This increases the energy carried through the medium. The increased vibrations result in increased intensity. The more frequently sound wave passes through the medium, the more are the vibrations created. The denser medium has particles more closely packed thus making the propagation of sound fasterį is the frequency of the sound wave. As the density of the medium increases, the intensity of the sound wave travelling through it will also increase. Sound Intensity is computed as the power carried by the sound waves per unit area in the direction perpendicular to that area. Scientifically speaking, your ears were able to catch the amount of energy through the vibration of the source per unit distance from the source, the physical quantity used to denote this is ‘Sound Intensity’ or ‘Acoustic Intensity’. Defining the Intensity of light, it is the power delivered by light per unit area of light. Luminous Intensity or Light Intensity is the amount of visible light emitted from the source/ brightness of light from the source per unit distance. The intensity of the radiation is the energy radiated from the system per unit area making a solid angle of. The core idea behind the definition and unit of measurement (Watt per meter square) remains the same for both the intensity of light and sound. Equation For Light Intensity Vs Distance. Intensity of Radiation Equation and the Solid Angle. The magnitude of intensity will depend on the strength and amplitude of a wave under propagation. Defining the Intensity of a wave, it is the quantity of energy that the wave conveys per unit time across the surface of the unit area, and it is also equivalent to the energy density multiplied by the wave speed. Light does not require a medium to travel while sound requires a medium. Light has transverse waves while sound has longitudinal waves. Light and sound, both are different types of waves. ![]()
