The frequency of a wave does not change as it passes from one medium to another. What will most likely happen if a light wave moves from the air into a solid?
O The wavelength of the light wave will increase.
O The speed of the light wave will decrease.
O The wavelength of the light wave will remain the same.
O The speed of the
fight wave will remain the same.

the chart show the masses and velocities of two colliding objects that stick together after a collision.

according to the law of conservation of momentum, the momentum of the object after the collision is  

answer

1,500

kg • m/s.

blue light is scattered in different directions by the tiny molecules of air. blue is scattered more than other colours because it has a shorter distance to travel which results in smaller waves. this is why we see a blue sky most of the time.
