Ultraviolet (UV) radiation, specifically UVA and UVB rays, are the wavelengths of light that can cause skin burning. UVB rays are primarily responsible for sunburn, while UVA rays penetrate deeper into the skin and contribute to skin aging and wrinkling. It is important to protect your skin from both UVA and UVB rays by using sunscreen.

What hapends when light hits a white surface?
When light hits a white surface, all the wavelengths of light are reflected off the surface uniformly, resulting in the surface appearing white to our eyes. This is because white surfaces reflect all visible wavelengths of light.
What is the separation of light into different wavelengths?
The separation of light into different wavelengths is called dispersion. This phenomenon occurs when light passes through a medium that causes the different wavelengths to travel at different speeds, leading to the splitting of the light into its component colors. This effect is commonly observed in phenomena such as rainbows and prisms.
What does color have to do with reflection?
Color affects reflection by determining what wavelengths of light are absorbed and which are reflected. The color of an object is determined by the wavelengths of light that its surface reflects. Different colors reflect different wavelengths of light, resulting in the perceived color of the object.
What is the color that an object appears to be determined by?
The color that an object appears to be is determined by the wavelengths of light that are reflected off the object and into our eyes. Different colors correspond to different wavelengths of light that are absorbed or reflected by the object's surface.
Why is a laser capable of burning things?
A laser is capable of burning things because it produces a focused beam of intense light energy. When this highly concentrated light energy interacts with a surface, it can quickly raise the temperature of that surface to the point of combustion, leading to burning or vaporization of the material.

What causes things to appear coloured?
Things appear colored due to the way light interacts with their surface. When light hits an object, certain wavelengths are absorbed while others are reflected. The reflected wavelengths are what our eyes perceive as color. Different colors are created by varying combinations of absorbed and reflected wavelengths.

Different colors reflect different wavelengths of light, resulting in the perceived color of the object.
What happens when light hits a blue surface?
Depending on the range of wavelengths that comprise the incident light, some of it may be absorbed and some may be reflected. If blue wavelengths are present in the incident light, then the blue is mostly reflected, and any other wavelengths are mostly absorbed. This is the main reason that the surface acquires the reputation of being 'blue'.

What object's color is dependent on?
An object's color is dependent on the wavelengths of light that are absorbed and reflected by its surface. The colors we see are the wavelengths of light that are reflected back to our eyes. Different objects absorb and reflect different wavelengths, giving them their unique colors.
What is reflected wavelengths?
Reflected wavelengths refer to the light waves that bounce off a surface instead of being absorbed or transmitted through it. The color we perceive is a result of the wavelengths of light that are reflected back to our eyes. Different surfaces reflect light in different ways, influencing the colors we see.
What must happen to all wavelengths of light?
All wavelengths of light must be absorbed, transmitted, or reflected when interacting with a surface. Depending on the material, some wavelengths may be absorbed, causing an increase in temperature, while others may be reflected or transmitted, affecting the color and appearance of the surface.
How are colors affected by light energy?
Colors are affected by light energy through a process called absorption. When light shines on an object, its surface absorbs certain wavelengths of light while reflecting others. The wavelengths that are reflected determine the color we see. Different colors are a result of different wavelengths of light being reflected off an object.
Why sunlight turn black colour into white?
Sunlight cannot turn black into white. However, a black surface may appear white in bright sunlight due to reflection of all the wavelengths of light from a shiny surface. The color black is actually the result of the absence of reflection of any wavelengths of light while the color white is the result of reflection of all the wavelengths of light.
