Answer:
Standing wave
Explanation:
A standing wave is a wave that does not propagate - instead, the oscillations due to the wave occur always in the same place. A standing wave is produced, for instance, when a string (tied on both ends) is made oscillating, or when two identical waves travel in opposite directions.
A standing wave is characterized by two particular types of points:
- There are some points where the amplitude of the oscillation of the wave is always maximum - these points are called anti-nodes of the wave
- There are some points where the amplitude of the oscillation of the wave is always zero - these points are called nodes of the wave.
Answer:
32.5 m/s
Explanation:
Velocity of a wave = frequency * wavelength
Velocity = 65 /s * 0.5 m
Velocity = 32.5 m/s
Answer:
Electromagnetic waves are created by oscillating charges (which radiate whenever accelerated) and have the same frequency as the oscillation. Since the electric and magnetic fields in most electromagnetic waves are perpendicular to the direction in which the wave moves, it is ordinarily a transverse wave.
Answer:
Chemical potential energy is the energy stored in the chemical bonds of a substance. The various chemicals that make up gasoline contain a large amount of chemical potential energy that is released when the gasoline is burned in a controlled way in the engine of the car. The release of that energy does two things
Explanation:
The formula for potential energy depends on the force acting on the two objects. For the gravitational force the formula is P.E. = mgh, where m is the mass in kilograms, g is the acceleration due to gravity (9.8 m / s2 at the surface of the earth) and h is the height in meters.
