Answer:

1. Longest wavelength - RED

Shortest wavelength - VIOLET

2. Highest frequency - VIOLET

Lowest frequency - RED

3. Highest energy - VIOLET

Lowest energy - RED

4. The frequency decreases, the wavelength gets longer.

5. As the frequency is increased, the perceived color gradually changes from red to orange to yellow to green to blue to violet. The eye doesn't perceive violet well. It always seems to look dark compared to other sources at equal intensity.

6. Frequency and wavelength have both direct and indirect relationships. If two waves are travelling at the same speed, they are inversely related. The wave with shorter wavelength will have a higher frequency while longer wavelength will have a lower frequency.

7. The energy of the wave is directly proportional to frequency, but inversely proportional to its wavelength. The greater the energy, the larger the frequency and the shorter (smaller) the wavelength.

8. Just as wavelength and frequency are related to light, they are also related to energy. The shorter the wavelengths and higher the frequency corresponds with greater energy. So the longer the wavelengths and lower the frequency results in lower energy.

Explanation:

1. Each color has a different wavelength. RED has the longest wavelength, while VIOLET has the shortest wavelength. When all the waves are seen together, they make white light.

2. When it comes to light, the highest frequency color is VIOLET (has the most energy), while RED is the lowest frequency (has the least energy).

3. Waves with the short-wavelength have the most energy. Red waves have a relatively long wavelength (700 mn range), and violet waves are much shorter - roughly half that. Because violet waves have the shortest wavelength of the visible light spectrum, they carry the most energy.

4. The number of complete wavelengths in a given unit of time is called frequency (f). As a wavelength increases in size, it's frequency and energy (E) decrease. From these equations you may realize that as the frequency increases, the wavelength gets shorter. As the frequency decreases, the wavelength gets longenerg
