What is frequency 50Hz?
WHAT IS 50 HERTZ? 50 Hertz (Hz) means the rotor of the generator turns 50 cycles per second, the current changes 50 times per second back and forth, direction changes 100 times.
Why do we use 50Hz frequency?
At that time, Motors are invented and scientists found that if we decrease the frequency of the electric supply, the eddy-current loss and hysteresis loss will gradually decrease. Therefore, the scientists decided to use 50 Hz instead of 60 Hz to reduce those losses.
Why frequency is 50Hz or 60Hz?
The Indian power supply rule of India is 220-250 Volts and 50 Hz, the major reason is the the Indian temprature is higher and High frequency can heat up wiring etc. The frequency of 50Hz need the voltage of 220-250 and frequency of 60Hz needs less voltage. The countries like US is using 60Hz.
Why the frequency of India is 50Hz?
Although 50 Hz was suitable for both, in 1890 Westinghouse considered that existing arc-lighting equipment operated slightly better on 60 Hz, and so that frequency was chosen.
Where is 50Hz used?
Most countries use 50Hz (50 Hertz or 50 cycles per second) as their AC frequency. Only a handful use 60Hz. The standard in the United States is 120V and 60Hz AC electricity….Listing per country.
| Country | Voltage | Frequency |
|---|---|---|
| Cambodia | 230V | 50Hz |
| Cameroon | 220V | 50Hz |
| Canada | 120/240V | 60Hz |
| Canary Islands | 230V | 50Hz |
Why does Japan use 50Hz and 60Hz?
One Country, Two Frequencies Japan’s 50Hz/60Hz divide. The divide is accidental and traces its origins back to the 1890s when first generators were brought to Japan from overseas. German generators operating at 50 Hz were the first ones to make it into Tokyo.
Which countries use 50Hz power?

| Country | Voltage | Frequency |
|---|---|---|
| Cambodia | 230V | 50Hz |

How is the classical wave theory of light related?
Since energy of the wave is dependent on the square of its amplitude, the classical wave theory predicts that if sufficiently intense light is used, the electrons would absorb enough energy to escape. There should not be any threshold frequency.
Why is there no threshold frequency in classical wave theory?
Since energy of the wave is dependent on the square of its amplitude, the classical wave theory predicts that if sufficiently intense light is used, the electrons would absorb enough energy to escape. There should not be any threshold frequency. 2. Almost immediate emission of photoelectrons
What did classical physics say about frequency of vibration?
The electrons in a hot object can vibrate with a range of frequencies, ranging from very few vibrations per second to a huge number of vibrations per second. In fact, there is no limit to how great the frequency can be. Classical physics said that each frequency of vibration should have the same energy.
How is heat and light explained in classical physics?
The explanation of classical physics: Light is an electromagnetic wave that is produced when an electric charge vibrates. (Strictly speaking, “vibrates” means any change in how the charge moves — speeding up, slowing down, or changing direction.) Now recall that heat is just the kinetic energy of random motion.
