Gamma rays have the smallest wavelengths and the most energy. X-rays have a higher energy level and shorter wavelengths than UV rays. Visible light is all the colors, consisting of red, orange, yellow, green, blue, indigo, and violet. Infrared light has longer wavelengths than visible light, making it invisible. Microwaves are used to transmit thermal energy. Radio waves have a wavelength lower than microwaves, and are used for sound and communication.

You have a bat-like echolocation system on your car, which emits a 20,000-Hz frequency sound that returns to the car in 0.18 s a

KiRa [710]

Answer:

The car travel 2.52 m

Explanation:

This problem gives us the time and speed of the car with the echolocation system, and they ask us for the distance traveled, we can use the report motion equation.

Let's start by calculating the relative speed of the two cars, which in this case is the initial mass because the second vehicle is at rest.

v = d / t

d = v t

d = 14 0.18

d = 2.52 m

The car travel 2.52m
