The ration of a frequency to its total frequency is called relative frequency.
frequency meter is used to measure the frequency of unknown frequency signal.
The frequency in a frequency table is the number of occurrences within each class width. The total frequency is the sum of all frequency's within all the classes.
Period = 1 / frequency
Given a frequency table,the first cumulative frequency is the same as the first frequency;the second cumulative frequency is the sum of the first cumulative frequency and the second [ordinary] frequency;the third cumulative frequency is the sum of the second cumulative frequency and the third [ordinary] frequency;and so on.An alternative definition is that the cumulative frequency for any value is the sum of all the frequencies less than or equal to that value.
Light is absorbed by the molecule.
absorbed
An orange that you eat has molecules and the color orange only has photons of a specific frequency.
No. Heating water increases the frequency of collisions of molecules.
Increasing the concentration increases the molecules' collision frequency.
Molecules or atoms in a gas are farther apart than in a liquid, so the collision frequency is lower.
High frequency (high pitch) sounds have a higher frequency than those of lower pitch. The air molecules of a high frequency sound, vibrate back and forth much more frequently.
Smell has nothing to do with frequency, amplitude, or wavelength. It is more about detecting the presence of certain types of molecules.
Molecules emit electromagnetic radiation in NMR spectroscopy.
Yes. All solids have a frequency, and when contacted by a sound of the same frequency, it causes the vibration of molecules in the solid. That is why singers can make a glass break vith their voice.
sound is simply the vibration of air molecules. so, sound occurs whenever air molecules are vibrated. but in order for us as humans to hear that sound, the air molecules have to vibrate within a certain frequency range
Glass has a natural frequency at which it vibrates, known as its resonant frequency. If you put energy into the substance at its resonant frequency, you will force it to vibrate or resonate (resonance is a forced vibration). So, tapping imparts energy to the glass molecules and causes them to resonate. This motion sets up a wave of vibration traveling through the glass. The vibrating glass causes air molecules to vibrate similarly. The vibrating air molecules are the sound wave that you hear (the frequency or pitch of the sound wave is the same as the resonant frequency of the glass). As the resonant wave moves through the glass, it moves the water molecules with it, creating a wave of water that you can see near the edge of the glass. The dragging water molecules effectively increase the mass (both the water and the glass molecules) and reduce the energy of the wave traveling through the glass. When the energy is reduced, so is the frequency of the wave in the glass, which is reflected in the pitch of the sound wave that you hear. In simpler terms, when you tap a glass with a lot of water in it, there are fewer vibrations because they have more trouble traveling through the higher mass. Thus, the lower pitch.
