Answer:

Option (C) is correct.

Explanation:

Speed of an object is defined as the distance covered per unit time. Speed is a scalar quantity It is composed only of the magnitude but the direction is absent. Mathematically, it is given by :

$v=\dfrac{d}{t}$

d = distance

t = time

So, the correct option is (c) " distance per time ". Its unit can be miles per hour or meter per second.

Answer:

"The wavelengths are the same for both. The width of slit 1 is larger than the width of slit 2."

Explanation:

The full question has not been provided, so I just copied this into the web and found this answer and explanation on quizlet:

"The wavelengths are the same for both. The width of slit 1 is larger than the width of slit 2.

D sin θ = m λ

if the wavelengths are the same, then if the angle is smaller, the slit width must be larger. The top photo shows a pattern that is more closely spaced. That means the angle is smaller. The slit width must be larger."

This answer/explanation should be correct, as we are looking at bright fringes and the formula being used corresponds to the parameters of the question.

Hope this helps!
