If this problem worsens, your electrical devices could end up receiving far too much or too little power and become damaged. Loose or bad connections are the major cause of fires and other safety hazards.
How is the rate of blinking related to the salience of flashing?
The rate of flashing has a powerful influence on the salience of flashing elements. The human eye is most sensitive to frequencies of 4-8 Hz (cycles/second). Very slow and very fast blinking are less attention-demanding than rates near that peak. The stimulus graphed in b flashes faster (higher f) than the one in a.
How is the rate of flashing related to the temporal frequency?
The temporal frequency is the number of flashes per unit of time. The contrast is the difference between the luminance of the bright and dark phases of the flashing (relative to twice the average luminance). Temporal Frequency. The rate of flashing has a powerful influence on the salience of flashing elements.
Which is the most sensitive frequency of flashing?
