Answer:

\huge\boxed{\sf Wavelength= 470\ m}

Explanation:

<u>Given Data:</u>

Speed of light = c = 3 × 10⁸ m/s (Constant)

Frequency = f = 640 kHz = 6.4 × 10² × 10³ Hz = 6.4 × 10⁵ Hz

<u>Required:</u>

Wavelength = λ = ?

<u>Formula:</u>

λ = c / f

<u>Solution:</u>

λ = 3 × 10⁸ / 6.4 × 10⁵

λ = 0.47 × 10³

λ = 4.7 × 10² m

λ = 470 m

\rule[225]{225}{2}

Hope this helped!

Most distances in the Galaxy are measured in light-years instead of meters. Why do you think this is the case?
lbvjy [14]

Answer and Explanation:

Most of the distances in the galaxy are measured in light years instead of meter because the distances in galaxy are very large and it is very difficult to measure in meters and light year is the largest unit of distance so it is very easy to measure large distances in light year so we prefer light year instead of meters for measuring distances in galaxy.

A leaf fell from a tree branch. The path it followed is shown in the diagram below.
prisoha [69]

The leaf fell at the crooked path instead of straight down because air currents and gravity applied changing and unbalanced forces to the leaf.

<h3>What is an air current?</h3>

An air current is defined as the changes in atmospheric pressure that causes the movement of air from one area to another.

When a leaf is detached naturally from the tree, it won't fall straight down to the floor but will fall a distance away from the tree due to the action of air current and some unbalanced forces.
