What is the ratio of a frequency to its total frequency?
The ration of a frequency to its total frequency is called relative frequency.
What is frequency meter?
frequency meter is used to measure the frequency of unknown frequency signal.
What is the frequency in a frequency table?
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.
How are frequency and wave period related?
Period = 1 / frequency
How do you make a cumulative frequency table?
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.
When the frequency of light matches the natural frequency of molecules in a material light is?
Light is absorbed by the molecule.
When the frenquency of light matches the natural frequency of molecules in a material light is?
absorbed
Does orange has?
An orange that you eat has molecules and the color orange only has photons of a specific frequency.
How does the concentration of reactants affect the rate of a reaction.?
Increasing the concentration increases the molecules' collision frequency.
Does molecular motion decrease when water is boiling?
No. Heating water increases the frequency of collisions of molecules.
Why is the collision frequency in a gas likely to less than in a concentrated liquid?
Molecules or atoms in a gas are farther apart than in a liquid, so the collision frequency is lower.
Meaning of high sounds?
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.
How can you classify smell based on different physical parameters like frequency amplitude or wavelength?
Smell has nothing to do with frequency, amplitude, or wavelength. It is more about detecting the presence of certain types of molecules.
What range of electromagnetic radiation is used in NMR?
Molecules emit electromagnetic radiation in NMR spectroscopy.
Can sound energy effect a solid?
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.
Describe what must happen to make a sound?
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
When you tap a glass with a little water in it It has a high pitch when you tap a glass with water filled to the top it has a low pitch why does this happen?
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.
