To solve this problem we will apply the concepts related to the principle of destructive and constructive interference. Mathematically this expression can be given as
Here,
n = Index of refraction
t = Thickness
m = Order of the reflection
= Wavelength
We have all of this values, therefore replacing,
Therefore the thickness of the oil slick is 233nm

Answer:
c. Sound travels slower than light.
Explanation:
We see any thing because of the light emitted or reflected by it. Whereas the sound is carried by the sound waves. The speed of light is more than the speed of sound. This is the reason the family saw the fireworks first and then heard the sound.
