160 degrees - The visual field of the human eye is _____ wide. 160 degrees 135 degrees 90 degrees 200 degrees AV equipment allows for adjusting the "whiteness" for optimal display. - Why is color temperature awareness important in the AV industry? The AV industry strives to set the standard for "whiteness." AV equipment allows for adjusting the "whiteness" for optimal display. People expect exact "whiteness" when viewing a display. "Whiteness" is subjective with ever changing...

waves: they are produced as a result of vibrations and do not transfer energy longitudinal waves: the particles vibrate parallel to the direction the wave is travelling e.g sound Previous Play Next Rewind 10 seconds Move forward 10 seconds Unmute 0:04 / 0:15 Full screen Brainpower Read More transverse waves: particles vibrate 90 degrees to the direction of wave travel e.g water and electromagnetic longitudinal frequency: the number of vibrations made by a p...
