what is the unit for a time taken that less than a second?

Question

i've heard that there is a new unit found for the time taken less than a second and it is called photosecond..
is it true??

Answer 1

We can describe fractions of a second by using SI prefixes. For example, a millisecond is 0.001 s. A microsecond is 10^-6 s.

Answer 2

x = previous digit(s) formerly 5: Rule: multiply x with the extensive kind a million greater advantageous than itself then affix 25 to the product. = (x[x + a million]) & 25 = x² + x & 25 occasion (15²): = (a million² + a million) & 25 = (a million + a million) & 25 = 2 & 25 = 225 OR = (a million * [a million + a million]) & 25 = (a million * 2) & 25 = 225 occasion (25²): = (2² + 2) & 25 = (4 + 2) & 25 = 6 & 25 = 625 OR = (2 * [2 + a million]) & 25 = (2 * 3) & 25 = 6 & 25 = 625 occasion (35²): = (3² + 3) & 25 = (9 + 3) & 25 = 12 & 25 = a million,225 OR = (3 * [3 + a million]) & 25 = (3 * 4) & 25 = 12 & 25 = a million,225 occasion (a hundred and five²): = (10² + 10) & 25 = (one hundred + 10) & 25 = one hundred ten & 25 = 11,0.5 OR = (10 * [10 + a million]) & 25 = (10 * 11) & 25 = one hundred ten & 25 = 11,0.5 occasion (a million,235²): = (123² + 123) & 25 = (15,129 + 123) & 25 = 15,252 & 25 = a million,525,225 OR = (123 * [123 + a million]) & 25 = (123 * 124) & 25 = 15,252 & 25 = a million,525,225 i'm hoping this helped.

Answer 3

The second (SI symbol: s), sometimes abbreviated sec., is the name of a unit of time, and is the International System of Units (SI) base unit of time.

SI prefixes are frequently combined with the word second to denote subdivisions of the second, e.g., the millisecond (one thousandth of a second) and nanosecond (one billionth of a second). Though SI prefixes may also be used to form multiples of the second (such as “kilosecond,” or one thousand seconds), such units are rarely used in practice. More commonly encountered, non-SI units of time such as the minute, hour, and day increase by multiples of 60 and 24 (rather than by powers of ten as in the SI system).

Answer 4

A fraction ? like 1/2 second

or are you refering to :-

Milli-second
Micro-second
Nano-second

They are all bits of seconds (second is the smallest unit of time by standard measurement)

Answer 5

1 milli second=10^-3 sec
1micro sec=10^-6sec

Answer 6

typically millisecond, thousandth of a second although with specialized equipmentm you can record times much faster than that

Answer 7

I am assuming you left out an "is" so that you are asking what "that is less than a second".

millisecond, microsecond, nanosecond, picosecond can all work.

Answer 8

1/10th of a second or 1/100th. What would you like?

Answer 9

millisecond(10^-3 s), nonosecond(10^-9 s), microsecond(10^-6s)ANS

Answer 10

Millisecond? microsecond? nano-, pico, or femptosecond? Whatever you like.
