You can compare the energy of two waves by calculating the square of their amplitudes. The wave with the higher amplitude will have more energy. Additionally, you can compare the frequencies of the waves - higher frequency waves generally carry more energy than lower frequency waves.
There's no dependence or connection between a wave's amplitude and its frequency.
You can compare the energy carried by two different longitudinal waves by calculating the wave's energy density, which is proportional to the square of the amplitude of the wave. The wave with the higher amplitude will carry more energy. Additionally, the frequency of the waves also affects the energy they carry - waves with higher frequencies carry more energy.
The beat frequency in a system with two sound waves of slightly different frequencies can be calculated by subtracting the frequencies of the two waves. The beat frequency is the difference between the two frequencies, which creates a pulsating sound when heard together.
Wave B has the higher frequency because frequency is the inverse of period. Mathematically, frequency = 1/period. Comparing the two periods, Wave B's period is smaller, so its frequency is higher.
In frequency or wavelength.
First of all I just want to tell that if we have to compare two things then we should always find a relationship between each other, its not always like a formula. it can be anything. Well the relationship between frequency and wavelength is given by Wavelength = Speed of light (299792458m/s) / frequency (/s) putting the values we get the wavelength of 56 Hz or 56 (per second) to be- 5353436.75m and of 2 Mhz to be 149.8m i think you could have just said 56 Hz has a bigger wavelength.
They must in phase and must have at least approximately the same frequency. If the two waves are in phase and have the same frequency, then they will have continuous constructive interference. If the two waves have different, but similar, frequencies then they will alternate between constructive and destructive interference.
IF they're both mechanical waves or both electromagnetic waves, AND they'reboth moving through the same stuff, THEN they both have the same speed.
Stationary waves are formed when two waves of the same frequency and amplitude travel in opposite directions and interfere constructively and destructively. If the frequency of the waves is less than the fundamental frequency, the wavelengths produced will be longer, making it impossible for the waves to meet the condition for constructive and destructive interference required to form stationary waves.
The wave with the higher frequency has more energy. This is because energy is directly proportional to frequency in waves - the higher the frequency, the higher the energy.
The two types of waves in radio waves are AM (amplitude modulation) and FM (frequency modulation). In gamma rays, there are no different types of waves as they are all high-energy electromagnetic waves.
