Because at night the sun goes down, which is a good thing for frequencies, because the sun is giving of radiation which is disrupting the frequencies. so at night nothing is disrupting the frequencies.

Why airplane sound is not heard during night?
I really don't get this question. I have been on thousands of night flights, and I have been through hundreds of airports, and I could always hear the engines, day or night. And, because your normal daylight traffic sounds are less, sound carries better at night, so you can hear the sounds of the aircraft farther at night, even farther than you can hear in the daytime. Higher frequencies definitely travel better at night, too. Unless ..., you were asleep, and didn't hear them? I am stumped.One possibility: There are fewer flights between midnight and 6 am: major airline traffic at most airports starts at about 7 o'clock in the morning. So, perhaps you don't hear so much aircraft sound, because they schedule fewer flights at night?
Why do radios work better at night particularily over Water This has been known since the dawn of Radio?
The answer I figured out (from old technical manuals) is in part Sound carries further at night even at audible frequencies owing to relative quiet (relativity) and also this would apply to overwater operations. Theother is one does not have to contend with solar-induced flares and scatter, as the sun has set. Radios work fine in daytime,but work better at night. This was known in the days fof Bill Marconi. sound and radio waves travel farther at night. right on.

Medium waves travel faster at night because.?
Because in day time the ionisation is less in the D layer of the Sky. So it absorbs the medium waves because of its lower frequencies. In night time the D layer vanishes and the Medium waves travel towards the F layer and reflected back to the earth from a long distance. That's why Medium waves are clearly heard in night times from a long distance.

How do I avoid truck scales?
