Inertia and force
PLEASE RATE THIS THE BRAINLIEST ANSWER! THANK YOU! :)
electromagnetic waves do not need any medium to travel but mechanical waves require a medium to travel regardless the state of matter that it is in (solid, liquid, gas)
Answer:
0.532
Explanation:
Your equation to find the second bright interference maximum is gonna be this: d sin (Θ) = m λ
First, find your variables.
λ = 580 · 10^-9
d = 0.000125
m = 2
Next, fill in the equation.
d sin (θ) = m λ
(0.000125) sin (θ) = (2) (580·10^-9)
Then isolate your variable.
θ = arcsin ( (2)(580·10^-9) / (0.000125) )
Run your equation and you will end up with 0.53171246 , which rounds to 0.532.
The main thing you have to watch out for is make sure you are calculating for the bright interference and not the dark interference, as well as checking you're calculating for the maximum, not the minimum.
I hope this helps :D

Explanation:
When you are saying "damped harmonic oscillator" it basically implies the motion of the oscillator will be damped, so the oscillation should decay with time.
For example, consider a harmonic oscillator inside water. so here the motion of the oscillator will be damped due to the friction with the water.
So, yes energy will be lost to friction in the motion.
Ok, now for your case, you are giving an external harmonic force, that will keep the oscillator moving. Also, it maintains a steady oscillatory motion, implies that whatever damping is causing because of the friction, is exactly nullified by the external harmonic force. Hence you get the steady oscillation.
