Answer:
Explanation:
Formula and givens
- λ = c / f
- λ is the wavelength
- c = the speed of light
- f = the frequency
- c = 3*10^8
- f = 7.89 * 10^14
λ = ?
Solution
λ = 3*10^8 / 7.89*10^14
λ = 3*10^8/7.89*10^14
λ = 2.36 * 10^7
λ = 236 nanometers. What you use as your solution depends on what what you have been taught.

Hello,
Although you can see the pencil, it appears broken in the glass of water. This is because <span>electromagnetic waves travel at different speeds through different media.

<span>We can use a simple equation to find the time for the feather to fall to the surface.
y = (1/2) g t^2
y is the height
g is the acceleration due to gravity
t is the time
t^2 = 2y / g
t = sqrt{ 2y / g }
t = sqrt{ (2) (1.40 m) / (1.67 m/s^2) }
t = sqrt { 1.6766 s^2 }
t = 1.29 seconds
It takes 1.29 seconds for the feather to fall to the surface.</span>
