Q3.What did you observe about the wavelengths and frequencies of the different colors of light?
Natalija [7]

Answer:

Explanation:

Q3.What did you observe about the wavelengths and frequencies of the different colors of light?

Q4. Do the frequencies of colors of light increase from red to violet?

Q5. What did you observe about the corresponding energies from red to violet?

wavelength times frequency =c=the speed of light

the higher the frequency, the shorter the wavelength

the different colors of visible  light are our good friend ROY G BIV

RED  ORANGE  YELLOW   GREEN   BLUE   INDIGO   VIOLET

As we go from red to violet, the wavelength decreases and the energy increases because the wave is vibrating at a higher number of vibrations per secomd. This is what "frequency' means, how many vibrations are there per second, how FREQUENT are thee.

the higher the frequency the more energy because the wave is vibrating faster.

the equation that relates this is Energy = h times frequency, where h is

Planck's constant = 6.262 x 10^-27 ERG-SEC

the frequency of vibration and therefor the energy of visible electromagnetic radiation (light) increase as we go across

ROY G BIV

A scientist is measuring the pressure that is exerted by each of the following gases in the atmosphere: carbon dioxide, oxygen,
Aleonysh [2.5K]

Answer:

Partial pressure

Explanation:

Since she's measuring the pressure exerted by each gas, it's partial pressure. If she were measuring the collective pressure, it would be total pressure.

How does a hydroelectric power plant convert energy?
Oksana_A [137]

Answer:

D. As water flows through the channels toward the turbines, it has kinetic energy. This is changed to mechanical energy as the water turns the turbines. Then the mechanical energy of the turbines is changed to electrical energy by the generator.

Explanation:

I hope this helps. :)
