Which of the following frequencies can be heard by the human ear -- a. 0.1 Hz b. 10 Hz c. 1000 Hz or d. 100000 Hz?
1000 Hz. The others are outside the range of human hearing. You can feel 10 Hz but not hear it. C. 1,000 Hz
What is the frequency of light with the wave length 1.0 x 10 to the -8 power?
(3 x 108 meters per second) / (1.0 x 10-8 meter) = 3 x 1016 Hz.
What color would you see when an electron in a hydrogen atom jumps from n equals 6 to n equals 2?
I am a bit rusty so I will do this the long way. Get frequency first(Hz). Hz = (3.29 X 10^15 Hz) * Z^2 * (1/n final^2 - 1/n initial^2) ( Z =1 for hydrogen, so no problems there ) Hz = (3.29 X 10^15 Hz) * (1/2^2 - 1/6^2) Hz = 7.31 X 10^14 Hertz Wavelength = speed of light/Hertz 2.998 X 10^8 m/s/7.31 X 10^14 Hz = 4.10 X 10^-7 meters that is 410 nanometers The color would be violet
How much time is 10 Hz?
Hz is short for hertz. It is not a time, but a frequency. Time is measured in seconds, Hz is equivalent to 1/seconds. Therefore, you can't convert between time and frequency.
How many gigahertz do have in a scientific notation?
1 billion Hz = 1 billion cycles / sec = 1 x 10^9 Hz = 1 x 10^9 cycles / sec
What does 10 to the 12th power have to do with sound and hearing?
The frequency range of human hearing is typically between 20 Hz and 20,000 Hz. When converted to scientific notation, the lower end of this range (20 Hz) is roughly 10 to the 1st power, the higher end of this range (20,000 Hz) is roughly 10 to the 4th power, and the midpoint of this range (10,000 Hz) is roughly 10 to the 4.5 power. So, 10 to the 12th power is beyond the range of frequencies the human ear can detect.
How much is 10 to the power of 9 Hz?
10 to the power of 9 (109) is one billion (US) or giga- so 109 Hz is 1 GHz.
How many watts are in a 60 Hz microwave oven?
A typical microwave is 750-800 watts. There are lower (and higher) power machines, but the 'normal' for general use is 750-800 watts.
What is the frequency of gamma rays?
Gamma rays have the highest frequency in the electromagnetic spectrum, typically ranging from 10 exahertz (10^19 Hz) to 10 zettahertz (10^23 Hz).
Difference between FREQUENCY 50 Hz 60 Hz?
10 Hz 10 Hz
How would you classify an em wave with a frequency of 10 hz?
10 to the power 7 Hz is 10 MHz, so that is HF (high frequency); this range of radio waves goes from 3 to 30 MHz.
How would you classify an EM wave with frequency of 10 7 Hz?
10 to the power 7 Hz is 10 MHz, so that is HF (high frequency); this range of radio waves goes from 3 to 30 MHz.
Which of the following frequencies can be heard by the human ear -- a. 0.1 Hz b. 10 Hz c. 1000 Hz or d. 100000 Hz?
1000 Hz. The others are outside the range of human hearing. You can feel 10 Hz but not hear it. C. 1,000 Hz
What is the period of a 10 Hz wave?
The period of a 10 Hz wave is 0.1 seconds. Period is defined as the time it takes for one complete cycle of the wave to occur, which is the reciprocal of the frequency. In this case, 1/10 Hz equals 0.1 seconds.
How do you run a 460 volt 60Hz motor with 460 volt 50Hz power?
If 50 hz is applied instead of 60 Hz, the speed of the motor will reduce by 10 hz equivalent. If you still want to keep the output speed equivalent to 60 Hz, you will have to use suitable gear box or so, to increase the speed to 60 hz equivalent.
What is the wavelength in nm of a light in a vacuum that has a frequency of 4.0 x 10 14 Hz?
The wavelength is 671 nm.
What is the energy of an electromagnetic wave with the frequency of 8 and times10 to the 12th power HZ?
The energy of an electromagnetic wave can be calculated using the equation E = hν, where E is energy, h is Planck's constant (6.626 x 10^-34 J·s), and ν is frequency. Plugging in the values: E = (6.626 x 10^-34) x 8 x 10^12 = 5.301 x 10^-21 Joules.
