To calculate the number of yellow light waves that will fit into a distance of 0.003 inches, you need to know the wavelength of yellow light. Yellow light typically has a wavelength of around 570-590 nanometers. With this information, you can use the formula: number of waves = distance/wavelength to find the answer.
Yellow light has the lowest frequency among the electromagnetic waves listed. The frequency of electromagnetic waves increases from radio waves to gamma rays, with yellow light falling in the visible light spectrum.
Yellow light has the lowest frequency among the electromagnetic waves listed.
When an object appears yellow, it is reflecting yellow light waves predominantly from the visible spectrum. This means that the object is absorbing other colors of light (like blue and red) and reflecting the yellow light, which is perceived by our eyes as the color yellow.
Sunlight is actually light waves of different frequencies. Some of these waves are part of the visible light spectrum (ROYGBIV), and therefore sunlight appears white, a combination of all the frequencies in the visible light spectrum. Light waves with lower frequencies appear more red or orange. Light waves with higher frequencies appear violet or blue. When sunlight shines down through the atmosphere, the particles in the air scatter the light waves of higher frequencies, therefore spreading the waves in different directions in the sky (This is why the sky appears blue). The lower frequency waves reach our eyes mostly undisturbed. Since sunlight has light frequencies dominant in yellow, that's the color we see.
Optical light waves are "Electromagnetic" waves. The colour seen is dependent on the wavelength of the light. Electromagnetic waves are transverse waves where the oscillation is 90 degrees to the direction of travel (unlike sound waves which are longitudinal).
