We start with two formulas; E = hf and f = c/λ
where:
E = Energy (eV)
h = Planck's Constant (6.626x10-34 (J-s))
f = frequency (Hz) of orange light at 650 nm
c = speed of light (3x108 m/s)
λ = wavelength of orange light (nm)
First, f = c/λ can be used to replace f in E=hf making the revised formula E = hc/λ;
Solve for E;
E = (6.626x10-34 * 3x108 ) / 650x10-9 = 3.0582x10-19 eV

Which colors of visible light have the highest and lowest frequency?
Red light has the lowest frequency and violet, the highest. The colors of visible light, in order from lowest frequency to highest: Red, Orange Yellow, Green, Blue, Indigo, Violet.
How do you Least to greats blue light X-rays microwaves orange light infrared radiation?
From least to greatest energy, the order would be: Infrared radiation < microwaves < blue light < orange light < X-rays This order is based on the electromagnetic spectrum, where the frequency and energy of radiation increase from left to right.
What are the colors of visible light in order of decreasing frequency.?
The colors of visible light, in order of decreasing frequency, are violet, indigo, blue, green, yellow, orange, and red. Violet has the highest frequency, while red has the lowest. This sequence represents the visible spectrum, which is part of the electromagnetic spectrum.
Why is frequency of red greater than violet?
The frequency of red light is lower than the frequency of violet light. This is because red light has a longer wavelength, which corresponds to a lower frequency. This difference in frequency is what causes red light to be more common than violet light in natural light sources.
Does red light have a higher frequency than green light?
No, red light is lower frequency than green light.
What is the significance of the wavelength 620nm in the context of optical measurements?
The wavelength 620nm is significant in optical measurements because it falls within the visible spectrum of light, specifically in the red-orange range. This wavelength is commonly used in various optical instruments and experiments due to its ability to be easily detected and measured accurately.
What has a lower frequency and longer wavelength Orange light or violet light?
Orange light has a lower frequency and longer wavelength compared to violet light. Orange light falls on the longer wavelength end of the visible light spectrum, while violet light falls on the shorter wavelength end.
What is the difference between orange light and yellow?
Compared to yellow light, orange light has: A LONGER WAVELENGTH!
Yellow light compared to orange light?
Yellow light has a shorter wavelength and higher frequency than orange light. This means yellow light appears brighter and more vibrant compared to orange light. Additionally, yellow light contains more energy than orange light.
Compare to yellow light orange light has?
... greater wavelength, lower frequency, less energy per photon.
What is the relationship of color of light and frequency?
Each colour of visible light has a different frequency. Red has the lowest frequency, meaning it has a long wavelength. Purple has the highest frequency and has a very short wavelength. The order is: red, orange, yellow, green, blue, purple. I hope this helps you!
What can be determined from the frequency of a light wave?
The frequency of a light wave corresponds to its color or wavelength. Higher frequency light waves have shorter wavelengths and are in the violet-blue end of the spectrum, while lower frequency waves have longer wavelengths and fall in the red-orange end of the spectrum. The frequency of light also affects its energy, with higher frequency light waves carrying more energy than lower frequency ones.
What is the relationship between the frequency of light and its color?
The frequency of light determines its color. Light with higher frequency appears blue or violet, while light with lower frequency appears red or orange. This relationship is described by the electromagnetic spectrum, where different frequencies correspond to different colors.
What is the difference between orange and green light?
Orange light has a longer wavelength and lower frequency than green light. This gives orange light a warmer appearance compared to the cooler, more vibrant appearance of green light. Green light is also perceived by the human eye more easily than orange light.
Which colors of visible light have the highest and lowest frequency?
Red light has the lowest frequency and violet, the highest. The colors of visible light, in order from lowest frequency to highest: Red, Orange Yellow, Green, Blue, Indigo, Violet.

Which color has a higher frequency yellow or red?
Yellow light has a higher frequency than red light. In the visible light spectrum, colors with shorter wavelengths have higher frequencies. Yellow light falls between green and orange in terms of wavelength and frequency, while red light has longer wavelengths and lower frequencies compared to yellow light.
