All waves are subject to the wave equation: wave speed = wavelength X frequency
Lets say that a wave is generated with a frequency f and a period T then we can see, T=1/f. If wavelength = 1.29m and the frequency is 256Hz, then v=lambda x f. If we work this out we can calculate the speed to be v=(1.29m)(256s); = 330 m/s
This is because the waves formed in the sea are caused by the blowing wind. As the wind blows over the water,stream of wind pushes the overlying water towards the direction it is moving.Therefore,the speed of water determines the size and shape of the wind.
Light waves are electromagnetic waves that consist of oscillating electric and magnetic fields. They travel through space at the speed of light and can move through a vacuum. Light waves have a wide range of frequencies, which determines their color and energy.
Frequency determines this.

Frequency determines this.
The amplitude determines the loudness of a sound wave.
Radio waves travel at the speed of light, which is the fastest speed possible in a vacuum. Infrared waves also travel at the speed of light, so both types of waves travel at the same speed.
If you are using an internet company that uses wireless, your connection speed depends greatly on the location and the waves travelling signaling you a better speed.
Ultrasonic sound waves travel at the same speed as lower frequency sound waves. The medium determines the speed at which a sound wave, which is mechanical energy, can travel. Sound waves travel faster in liquids than in a gas (like air), and travel faster still in solids. The speed at which a sound wave travels is generally independent of the frequency of that sound. Use the link below for more information.
Radio waves travel at the speed of light, which is approximately 300,000 kilometers per second in a vacuum. Infrared waves also travel at the speed of light, so both types of waves travel at the same speed.
Radar works by sending out radio waves that bounce off objects in its path. By measuring the time it takes for the waves to return, the radar determines the distance and speed of the object. This information is then used to track the object and calculate its location.
The raising and lowering of the whistle's pitch due to the alteration in the relative speed of the whistle as it goes by you, described by two terms that can be discovered by reading your homework assignment.
