While these ingredients are more common, cordials may also be created by using juices or fruit pulp as the main ingredient. In addition, a cordial is also used to describe a liqueur that has been created by blending brandy with spices and herbs.Sweet Treat.

Calculate the length of a radio wave picked up by a car radio tuned to. The radio wavelength equals the velocity of the radio wave divided by the frequency. In this case, the frequency is 89.3 MHz (8.93 X 107 Hz) and the velocity is the speed of light (3.0 X 108 m/s, for all waves in the electromagnetic spectrum). The calculations are as follows:
The frequency of a wave is one of its most fundamental principles, and the range of possible frequencies makes up something known as the electromagnetic spectrum. This runs from low-energy radio waves to high-energy gamma rays. Unlike its wavelength, the electromagnetic frequency of a wave doesnât change. Electromagnetic radiation is a type of wave that travels at the speed of light. It is a transverse wave, which means it oscillates up and down in a direction opposite that in which it is moving. The electromagnetic frequency of a wave is defined as how many times the peak of this oscillation moves past a point each second. This has a major effect on the properties of the wave, including its energy. The wavelength, on the other hand, is the distance between two peaks of the wave or, in other words, the length of a full cycle.
