B) energy and wavelength decrease
C) energy decreases, wavelength increases
D) energy increases, wavelength decreases
When the frequency of the waves increases, its energy increases, while the wavelength decreases.
• A travelling disturbance, which mediates energy from one place to another is known as a wave.
• The tendency to do work or cause a change is known as the energy.
• Waves can be determined with the help of frequency and wavelength.
• In a given unit of time, the number of complete wavelengths is known as frequency.
• With the increase of the size of wavelengths, its energy and frequencydecreases.
• There are two basic kind of waves, that is, electromagnetic and mechanical waves.
• The waves, which can travel through a medium or a vacuum is known as the electromagnetic waves.
• The waves with long wavelengths comprise less energy than waves with short wavelengths.
Thus, correct answer is option d, that is, energy increases, wavelength decreases.
To know more about:
As the frequency is how many waves pass a fixed point in certain amount of times. This means that the waves get closer together and, therefore, the wavelength decreases. It also means that the wave has more energy.
Answer: D) Energy increases, wavelength decreases
B. For the balloon to float in air, what two factors might have changed about the balloon?
Answer those two questions of you know the answer.
Answer: because the vibration is of very short amplitude, at atomic scale.
Explanation:
The rocks are solid objects.
The solid physical state is characterized because the particles of the solid substances (molecules or atoms) are closely packed in fixed positions.
So, the particles of solids cannot slip (pass) on each other. Nevertheless, yet the particles vibrate rapidly. This vibration is the manifestation of the thermal energy of the substance.
The vibration of the atoms or molecules in a solid is of very short amplitude: it happens at atomic level, so that vibration is not visible. The vibration may be detected by x-ray diffraction but not by visible light.
