In most cases, malaria is transmitted through the bites of female Anopheles mosquitoes. There are more than 400 different species of Anopheles mosquito; around 30 are malaria vectors of major importance. All of the important vector species bite between dusk and dawn.
When replayed at normal speed, time appears to be moving more slowly. A term for creating slow motion film is overcranking which refers to hand cranking an early camera at a faster rate than normal (i.e. faster than 24 frames per second).
So you can see only 60 frames in one second, so it takes two second to see 120 frames, bt it takes only one second to record 120 frames. So obviously the time takes longer for playing than recording, i.e. the video is slowed down and you will see the apple falling slowly.
