What statement best describes ultraviolet waves?
Ultraviolet waves are a type of electromagnetic radiation that have shorter wavelengths and higher frequencies than visible light. They are present in sunlight and can cause sunburn and skin damage with overexposure.
Why does black absorb sunlight?
Black absorbs sunlight because it contains pigments that absorb a wide range of wavelengths of light, including those in the visible and near-infrared spectrum. This absorbed light energy is then converted into heat, which raises the temperature of the black object.
Do visible light waves have higher frequencies than radio waves?
Yes, visible light waves have higher frequencies than radio waves. Visible light waves fall within the range of frequencies on the electromagnetic spectrum that is higher than radio waves.
What two things have to be present for a rainbow to form?
For a rainbow to form, two things have to be present: sunlight and water droplets in the air. The sunlight is refracted and reflected within the water droplets, causing the colors of the spectrum to be visible as a rainbow.
Is sunlight an electromagnetic wave?
yes,sunlight is an electromagnetic wave which consists of electric and magnetic fields which are mutually perpendicular to each other and these two are perpendicular to the direction of wave propagation

Why is the sunlight reaching the earth yellowish?
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.
Why does black absorb sunlight?
Black absorbs sunlight because it contains pigments that absorb a wide range of wavelengths of light, including those in the visible and near-infrared spectrum. This absorbed light energy is then converted into heat, which raises the temperature of the black object.
What radiation lies at frequencies just blow the frequencies of visible light?
infrared
What is in the sunlight and what is in darkness?
Sunlight contains visible light, ultraviolet (UV) radiation, and infrared radiation. Darkness lacks the presence of visible light, although other forms of radiation may still be present depending on the environment.
Why must there be sunshine and rain in order to for a rainbow to be seen?
The sunlight whenpassing through water droplets in air is refracted into different colours making a rainbow. Sunlight (white light) is composed of visible rays at different frequencies. Different frequencies bend when passing through water at different angles and can be seen separately.
Do visible light waves have higher frequencies than radio waves?
Yes, visible light waves have higher frequencies than radio waves. Visible light waves fall within the range of frequencies on the electromagnetic spectrum that is higher than radio waves.

How do you perceive the different frequencies of light waves?
Different frequencies of visible light are perceived as different colors.
What is the difference between the colours of visible light?
their wavelengths (frequencies)
Is sunlight an electromagnetic wave?
yes,sunlight is an electromagnetic wave which consists of electric and magnetic fields which are mutually perpendicular to each other and these two are perpendicular to the direction of wave propagation
Is visible light used for photosynthesis?
Yes,visible light is used. Frequencies of blue and red absorbed effectively
