It varies from field to field.
In computers, it refers to the amount of time (typically measures in milliseconds [1/1000th of a second), microseconds [1/1,000,000th of a second], nanoseconds [1/1,000,000,000th of a second] and sometimes picoseconds [1/1,000,000,000,000th of a second]
For example, a 1 GHz CPU has a reaction time of 1/1,000,000,000th of a second, or 1 nanosecond, give or take based on various other influences. (A Hertz is a measurement of frequency per second. 1 Hz = once a second. 1kHz = 1,000 times a second, etc.)
A reaction time is born but is made at the same time. While you grow older and use your reaction more, your reaction time will become faster and better. So, your reaction time isn't born nor made.
the fastest reaction time is 0.04 secs!!
how does rate of reaction changes with time
Fear can improve (shorten) reaction time.
The reaction time of everyone is different. Being a college student doesn't play a role in your reaction time.
Alligators have a reaction time of 50 milliseconds. This reaction time is most likely enabled by their super sensitive skin.
Does the age of a person effect the reaction time
Every sport uses reaction time.
no they have short reaction time
As the temperature increases, the reaction time decreases.
Reaction time shortens from infancy into the late 20s. Then reaction time slowly increases until the 50s and 60s. Reaction time lengthens faster as the person gets into their 70s.
