Refraction is the bending of a wave when it enters a medium where its speed is different. This phenomenon is explained by the conservation of energy and conservation of momentum. 

Law of Conservation of energy states the total energy of an isolated system remains constant.

law of conservation of momentum states that in a closed system the total momentum is constant.

<span>In refraction, when a medium changes, the phase velocity also changes but its frequency does not; it remains constant. </span>

The height to which a 50 kg object must be lifted to increase its potential energy to 5,000 joules is about:
Diano4ka-milaya [45]

Explanation:

potential energy = mass × gravity force × height

5000 = 50 ×10 ×h

5000= 500×h

h = 5000÷500

h = 10 m

Combine newton's 2nd law and hooke's law for a spring to find the acceleration of the block a(t as a function of time.
USPshnik [31]
2nd law: F = ma 
hook's law: F = -kx

ma = -kx
a = \frac{d^2x}{dt^2} = - \frac{k}{m} x

try solution: x = e^{ \lambda t} , \frac{dx}{dt} = \lambda e^{ \lambda t}, \frac{d^2x}{dt^2} = \lambda^2 e^{ \lambda t}

\lambda^2e^{ \lambda t}= - \frac{k}{m}e^{ \lambda t}

divide by: e^{ \lambda t}

\lambda^2 = - \frac{k}{m}

solution:
a =-\frac{k}{m}e^{i \sqrt{ \frac{k}{m} }t }
