I know Hz is measured per second, but what per second??

Hz is the unit for 1 cycle/second. The cycle refers to a wave's cycle and it's from the peak of one wave to the trough of the next

Cycles per second. Think of it as things done or cycles completed per second. Therefore, finding the inverse of frequency would give you how many cycles or things were done.

Hz is unit for frequency, and it equals to 1 cycle / second.

Is hz the same as s-1?

Yes, the units for Hz is s-1 and it basically means that there is one cycle per second.

The units for hertz is one cycle per second.

cycle .s^{-1}

Posted: **Thu Oct 17, 2019 10:48 pm**

The unit for Hz, which is a frequency is s^-1. However, it means cycles per second.

Posted: **Thu Oct 17, 2019 11:25 pm**

As mentioned above Hz is equivalent to s^-1, which is why you can often cancel out Hz when you have m/s in your calculations.

1/s

Posted: **Fri Oct 18, 2019 12:44 am**

1 cycle * s^(-1)

1 Hz = 1 cycle/second but is expressed as 1s^-1 most typically which will help you many times to clearly see unit calculation. Also when you end up with the unit s^-1 if the problem doesn't clearly say to express it like that, it is appropriate to change it back to Hz.

The units for hertz is one cycle per second (s^-1)

Posted: **Sat Oct 19, 2019 7:06 pm**

The units for hertz is cycles per second, but the cycles can refer to a number of different cycles so it's -s.

Hertz is a unit of frequency measured as cycles per second.

Posted: **Sun Oct 20, 2019 6:14 pm**

Hertz can also be expressed as s^-1, which means one cycle per second

Hz is one cycle per second (1/s) and it is the same as s

Posted: **Sun Oct 20, 2019 7:58 pm**

1/s. For example, 13 Hz = 13/second would be 13 cycles per second

Posted: **Sun Oct 20, 2019 8:07 pm**

s^-1

refers to cycles per second

refers to cycles per second

Posted: **Sun Oct 20, 2019 8:47 pm**

Hertz is cycles per second and it can be written as 1/s or s^-1

Posted: **Sun Oct 20, 2019 8:49 pm**

The unit for hertz is the number of cycles per second which basically measures frequency.

Posted: **Sun Oct 20, 2019 8:51 pm**

cycle per second (s-1)

Posted: **Sun Oct 20, 2019 8:53 pm**

number of cycles per second (s^-)

Posted: **Sun Oct 20, 2019 9:50 pm**

Hz would be s^-1 which implies 1 cycle per second

Posted: **Sun Oct 20, 2019 9:52 pm**

I cycle per second

Posted: **Sun Oct 20, 2019 9:54 pm**

1 Hz is counted as 1 cycle per second

Posted: **Sun Oct 20, 2019 9:59 pm**

Hz is a unit of frequency that denotes the number of complete cycles per second. 1 Hz=1/sec

Posted: **Sun Oct 20, 2019 10:11 pm**

1 Hz = 1 cycle/second

Posted: **Sun Oct 20, 2019 10:29 pm**

Hertz refers to s^-1. This is justified by the fact that c = v λ; c is in units of m/s, λ is in units of m, therefore leaving v in units of s^-1.

perfect explanation

Posted: **Sun Oct 20, 2019 11:07 pm**

Hertz essentially indicates how many "cycles" of the wave have passed a certain point in one second. In simple terms, 1Hz = 1cycle/second. The "cycle" is implied.

Hz, S-1, cycles per second they all mean the same thing

Posted: **Sun Oct 20, 2019 11:18 pm**

Hz is equivalent to 1 cycle/second.

1 Hertz (Hz) = 1 cycle per second (s^-1)

Frequency (v) is measured in Hertz

example:

an electric field that oscillates at 6.4x10^14 Hz (blue light) completes 6.4x10^14 cycles per second

an electric field that oscillates at 4.3x10^14 Hz (red light) completes 4.3x10^14 cycles per second

red light has a lower frequency than blue light

Frequency (v) is measured in Hertz

example:

an electric field that oscillates at 6.4x10^14 Hz (blue light) completes 6.4x10^14 cycles per second

an electric field that oscillates at 4.3x10^14 Hz (red light) completes 4.3x10^14 cycles per second

The unit is 1/s which is essentially s^-1

1 cycle/second

Hz is the measurement of frequency and it is 1 cycle per second

Posted: **Sun Nov 03, 2019 9:15 pm**

1 cycle/second or in calculation basically s^-1

Posted: **Sun Nov 03, 2019 11:03 pm**

s^-1, or one cycle per second!

Posted: **Sun Nov 03, 2019 11:04 pm**

1 cycle/second!
