E = hf
E : photon energy
h : Plank's constant 6.63×10^-34
f : frequency
Hope it helped!
Frequency of the wave is 2 per second
Explanation:
- Frequency is the number of times waves pass at a particular point of time. Here, time period = 0.5 s
- Frequency is given by the formula
f = 1/T, where f is the frequency and T is the time period
⇒ f = 1/0.5 = 2 per second
Answer:
The answer is C.
Explanation:
Let's take a glass of water as an example. Now, shine a flashlight on it. See it bend the light into a rainbow? That is a example of refraction. When the light enters the water, the water actually slows down and changes its direction, causing the light to come out the other side in a different way. Since water is very dense, it can bend the water and make it different.
Hello,
When a skydiver first jumps off a plane potential energy (<span>energy in an object due to its position) will be converted into kinetic energy (</span><span>energy which a body possesses because of its motion.)
