Are there more radio stations during the day than at night

Actually, it's just as much!

Radio waves that propagate by relying on reflections from the ionosphere are called skywaves. What is the ionosphere? The earth is surrounded by a thick atmosphere, and within a range of 50 kilometers to hundreds of kilometers above the ground, some gas molecules in the atmosphere lose electrons due to irradiation from sunlight, that is, ionization, producing positively charged ions and free electrons, this atmosphere is called the ionosphere.

The ionosphere exhibits different properties for different wavelengths of electromagnetic waves. Experiments have proved that microwaves with wavelengths shorter than 10 m can pass through the ionosphere, and long waves with wavelengths longer than 3,000 km will be almost completely absorbed by the ionosphere. For medium-wave, medium-short-wave, short-wave, short-wave, short-wavelength wavelengths, the shorter the wavelength, the less it is absorbed and the more it is reflected by the ionosphere.

Therefore, short waves are best suited to propagate in the form of sky waves, which can be reflected by the ionosphere to thousands of kilometers away. However, the ionosphere is unstable, with high levels of ionization during the day and low levels of ionization at night when exposed to sunlight. Therefore, its absorption of medium and medium and short waves is weakened at night, and at this time, medium and medium and short waves can also propagate in the form of sky waves.

This is why the radio is able to listen to many medium- and medium-wave radio stations from far away at night.

Because the environment at night interferes less with electromagnetic waves than during the day, more radio stations are received.

The transmission of radio programs takes place at radio stations. The sound waves of the broadcast program are converted into audio frequency electrical signals through electroacoustic devices, and amplified by the audio frequency amplifier, and the oscillator generates a high-frequency equal amplitude oscillation signal; The modulator makes the high-frequency equal-amplitude oscillation signal modulated by the audio signal; The modulated high-frequency oscillation signal is amplified and sent to the transmitting antenna line to be converted into radio waves for radiation.

The reception of radio broadcasts is achieved by radio. The receiving antenna of the radio receives radio waves from the air; The tuning circuit selects the signal of the desired frequency; The geophone restores the high-frequency signal into an audio signal; The audio signal obtained after demodulation is amplified to obtain sufficient driving power. Finally, the broadcast content is restored through electroacoustic conversion.

Many of our emotions will be infinitely amplified at night, so listening to the radio late at night will make us very vulnerable, and it is easy to associate some of our own experiences because of the content on the radio, and many people who are easily sentimental will break down and cry.

The more I listened, the more energetic I became, and I didn't want to sleep when I heard it.

I especially like to listen to Jinshan's night talk, which is actually about some miscellaneous things in life, all kinds of emotional troubles, all kinds of trivial things in life, point it out to the point, and then put forward some methods with high feasibility.

I feel that this may be the earliest chicken soup for the soul, I often listen to this show in the middle of the night, sometimes it is quite touching, the more I listen, the more energetic, sleep or something, just don't want to.

Let's be honest, it may be because there are too many entertainment methods now, and listening to the radio late at night is really unacceptable. Some time ago, I deliberately used my mobile phone to listen to FM, so that I could hear some songs or other programs. But basically, I can't calm down and listen carefully, and I always want to watch the news or watch movies.

I have the habit of listening to the radio late at night, which may be a habit developed since childhood, when I was a child, there was no electricity at home, there was a radio at that time, and at night the family listened to all kinds of radio programs, because I worked outside during the day, and only had time to listen at night, whenever I listened to the radio, I couldn't help but think of what scene I had when I was a child.

I like to listen to the radio late at night, but when there is a very magnetic male voice, or a gentle female voice, when it rings next to my ears, I feel that the whole world is quiet, and it is still accompanying me to think.

Sometimes I feel that listening to the radio in the middle of the night is not listening to stories, but companionship, and this companionship touches me.

I don't usually listen to it, but that experience was really special. I was driving home in the evening, and I listened to the radio on the way. Ghost stories were being told on the radio, and it happened to be ghost stories in taxis.

I felt that there was a ghost waiting for me behind me, and I was so frightened that I shivered and immediately turned off the radio.

Listening to the radio in the dead of night is very enjoyable, it can purify the soul and comfort the soul, especially when listening to some emotional programs, you will feel empathy, and many warm true stories will make people feel comforted in the dark night.

I felt that the world around me was quiet, without the noise of the big city, without the roar of cars, and the only thing left in my world was me and the sound of the radio.

It's a very rare way to relax, and every day my stress disappears in this moment of emptying my time to find hope in life.

I like to listen to the radio before I go to bed, if I'm not very sleepy, I listen to what he says, to feel that feeling, occasionally listen to chicken soup for the soul to cheer myself up, and if I'm sleepy, I set a timer and feel someone whispering in my ear, and I will sleep comfortably.

I think Samsung also has a radio station, which is a lonely experience, because only the kind of people who are very lonely at heart will listen to that kind of radio in the middle of the night. If it were happy and happy people. It's rare to mix in the late-night radio for a day to dispel the loneliness in your heart.
