Doubling the frequency of a wave at constant speed O causes he wavelength to increase and crests to be farther apart o does not affect wavelength if speed is constant O causes the wavelength to be smaller and thus farther apart O causes the wavelength to be smaller and crests closer together

The speed of electromagnetic waves in air is 3.0 x 108 m s-1. Calculate: a) the wavelength of light of frequency 6.0 x 1014 Hz (quote your answer in nm) b) the frequency of radio waves of wavelength 1.25 km.

What do all waves do? Move a medium side to side. Cause energy to move from one place to another. Make people stand up and sit down, going around a stadium. Say good bye to people. What is the difference between Mechanical waves and Electromagnetic waves? Mechanical waves are all transverse waves like most Electromagnetic waves. Mechanical waves are all longitudinal waves like most Electromagnetic waves. Mechanical waves need a medium/material to move through, Electromagnetic waves don't need a medium/material to move through. Electromagnectic waves are all longitudinal waves like many Mechanical waves.

4) Radio telescopes receive radiowaves from distant stars. If such a wave has a wavelength of 24 cm and travels at the speed of light (c = 3.00 x 108 m/s), what is the frequency?

Light is said to be a transverse wave. What is it that varies at right angles to the direction of the motion? The electric and magnetic fields travels at right angles to the direction of the motion. The frequency varies at right angles to the direction of the motion. The amplitude travels at right angles to the direction of the motion. The wavelength travels at right angles to the direction of the motion.

A light wave with a frequency of 5.2 x 1014 Hz has a speed of 3 x 108 m/s while traveling through a vacuum. What will be the speed of a light wave with frequency 7.5 x 1014 Hz in the same vacuum? 3 x 106 m/s A 3 x 108 m/s B 2 x 109 m/s 1 x 109 m/s D

What is the result of a wave reflecting off a fixed boundary?   The reflected wave has the same amplitude, but is upside down.   The reflected wave has the same amplitude and the same orientation.   The reflected wave will have a smaller amplitude than the incident wave.   The reflected wave will have a larger amplitude than the incident wave.

The equation of a wave is given by y=4sin[0.5π(x-3t)] where x and y are given in meters and t in seconds. What is the wavelength of the wave? 0.5 m 1 m 2 m 3 m 4 m
