if the blue light carries more energy should this mean anything about the preferred color of warning lights and stoplights
The blue part of the spectrum has more energy than the red part.
No, blue and red visible light have different wavelengths. if you see the rainbow, blue and red can been seen on separate stripes which means they have different wavelengths.
Visible light. It has a higher frequency so more energy.
The highest frequency in the visible portion of the electromagnetic spectrumis the last color you can see on the blue/violet end of the rainbow.
When visible light enters water, shorter wavelengths (blue and violet) are absorbed and scattered more by water molecules than longer wavelengths (red and orange). This is why water appears blue as it absorbs the shorter blue wavelengths and reflects them back. Hence, longer wavelengths penetrate deeper into water, making red light the most visible at greater depths.
The blue part of the spectrum has more energy than the red part.
Because blue light has a shorter wavelength than most of the other wavelengths of visible light, so there's less diffraction more details of the object will be visible under blue light.
blue light is a part of visible spectra
No, blue and red visible light have different wavelengths. if you see the rainbow, blue and red can been seen on separate stripes which means they have different wavelengths.
When a star is blue it means it is putting out light mostly in the ultraviolet spectrum which is of a higher energy than infared light, or light in the visible spectrum. This means the star has more energy and heat.
Visible light. It has a higher frequency so more energy.
it have more energy than visible light
Lightning appears blue because of the way light is scattered in the Earth's atmosphere. The blue color is a result of the nitrogen and oxygen molecules in the air absorbing and scattering the shorter wavelengths of light, such as blue and violet, more than the longer wavelengths. This causes the blue light to be more visible during a lightning strike.
The blue wave of light has a shorter wavelength and higher energy than the red wave of light. This leads to blue light being scattered more easily by the atmosphere, which is why the sky appears blue. On the other hand, red light is less scattered and is more visible in the evening when the sun is low in the sky.
No. Some are longer trhan others, but they are all very short. Light visible to the human eye has wavelengths ranging from a little more than 100 micrometers (infrared) to less than 1 nanometers (ultraviolet). In reference to visible light, infrared is referred to as long wavelength and ultraviolet as short wavelength light. I can't remember the units, but the human visible area is from about 400 (deep blue) to 700 (red), so a rather more restricted range than implied above. All those wavelengths are indeed very short.
The sky appears blue because air molecules scatter shorter-wavelength blue light more efficiently than other colors. This scattering effect causes the blue light to be more visible to our eyes, giving the sky its characteristic blue color.
Blue light has a lower frequency than violet light. Violet light has the highest frequency in the visible spectrum, while blue light has a slightly lower frequency than violet light but higher than green light.
