The Magic of Light
Water Refraction Experiment: In this video, someone uses the law of refraction. When light passes through air, the glass, and the water, the angle the light ray makes with the normal of the surface is changed every time it passes through the different medium. The glass, the air, and the water have different […]
Wave Interference
These are the Constructive Interference. When a crest/trough meets crest/trough from another source, their energies combine to result in a greater displace, providing a bigger crest/trough. This is the wave that has a destructive Interference. When the crest and the trough meet, they cancel each other out, and the wave becomes flat (it is hard […]
Exploring Waves Lab
This is mechanical wave because the wave is not repeating; single disturbance. This is periodic waves because the wave is repeating; repeating disturbances. This is transverse waves because the spring is pulled side ways. This is longitudinal waves the wave is moving to the same direction as the energy transferred.
Archimedes Challenge
History of Archimedes screw The Archimedes screw is the machine to raise water with less effort than lifting buckets. It was invented by Greek scientist Archimedes, to pulling water up easily with less work. The King called upon Archimedes for assistance to empty rainwater from the hull of one of his ships. Historians mentioned that […]
Newton’s Laws Video Blog Post
In the Newton’s first law of inertia, it states that when an object is stationary, it will continue to be stationary until outside forces act on it. At the same time, if an object is already in motion, it will continue to be in motion until outside forces act on it. In the video, a […]
