Reciprocal of frequency gives the period
SO T = 1/ n
Or T = 1/40000 = 25 microsecond

What sound level is dB is required for a 1 sone loudness at frequency 50 Hz?
1 sone = 40 dB at 1 kHz.
What are sones?
Sones are a unit of perceived loudness developed by Stanley Smith Stevens in 1936. In acoustics, loudness is the subjective perception of sound pressure. According to Stevens' definition, the sone is equivalent to 40 phons, which is defined as the loudness level NL of a 1 kHz tone at 40 dB SPL. The number of sones to a phon was chosen so that a doubling of the number of sones sounds to the human ear like a doubling of the loudness, which also corresponds to increasing the sound pressure level by 10 dB.

Compared to a sound of 40 decibels a sound of 60 decibels is?
100 times intensity.
What is wavelength of 40 hertz?
1 pulse every 40 microseconds is equal to a frequency of 25,000 hertz
What sound level is dB is required for a 1 sone loudness at frequency 50 Hz?
1 sone = 40 dB at 1 kHz.
What is the frequency of simple transmitter?
40 kHz
What is the frequency of simple IR Transmitter?
40 kHz
What is available in very small package to produce 100 KHZ to 400 KHZ sound?
You'll have to search the internet for "ultrasound transducer" and "ultrasonic transducer". Having just done that, we suspect you may have a tough time finding devices for that range of frequencies. It seems that the low-cost hobby devices operate in 40 to 80 KHz, while medical ultrasound imaging operates at a few MHz. We're curious as to why you've selected that particular range of frequencies. Good luck. No human or animal can hear that sound.
What is the minimum sample rate required to to record a frequency of 20 kHz?
According to the Nyquist theorem, a sample rate of double the frequency is required to record it, so 40 kHz .
Guinea pigs hearing?
Pigs can hear in audio tones in a range of about 40 Hz to about 40 KHz.
What is a giraffes pulse?
20-40 bpm
What is a normal pulse deficit?
23-40
What is the bandwidth of a signal that ranges from 40KHz to 4 MHz?
Solution Let fh is the highest frequency and fl is the lowest frequency. Bandwidth = fh - fl = 4000 - 40 KHz = 3960 KHz = 3.96 MHz
How many AM broadcast stations can be accommodated in a 100 KHz bandwidth if the height frequency modulating a carrier is 5KHz?
40
What is the normal range for pulse deficit?
A pulse deficit is the difference between an actual heart beat and the pulse felt in the wrist or neck. Normal pulse deficits can be felt in someone with a pacemaker.
What is the pulse of a healthy adult horse?
Between about 24 and 40
