Question

How to calculate threshold frequency??​

Answer 1

The 60% method – this calculates the threshold level by adding 60% of the range of your heart rate to the resting pulse rate.

For example: if a person's resting pulse rate = 80.

• and his maximum rate = 180.
• then the range = (180 - 80) = 100.
• 60% of the range = 60.
• so the threshold rate = (80 + 60) = 140.

Answer 2

Answer:

photoelectric threshold frequency, symbolized by the Greek letter nu with subscript zero, ν0, is that frequency at which the effect is barely possible; it is given by the ratio of the work function symbolized by the Greek letter psi, ψ, to Planck's constant (ν0 =
