Because they behave just like all the electromagnetic waves of the spectrum. Same equations, just shorter wavelengths and more energy.
Hope you get it :)
Answer:
37.5 m/s
Explanation:
Using the law of conservation of energy, potential energy equals kinetic energy hence
Therefore
where g is the acceleration due to gravity, m is the mass of the object, h is the height and v is the speed of the roller coaster
Taking g as 9.81 then
Sound is a kind of longitudinal (and mechmaical too) wave i.e the medium to transfer energy from one point to another though vibrations.
It is produced with the production of vibrations.
Answer:
They are reflected.
Explanation:
Red light is absorbed while green light is reflected, causing the color to be green in human eyes.
