Light rays are scattered when they encounter particles or objects that are much smaller than the wavelength of the light. This interaction causes the light to change direction and spread out, giving rise to phenomena such as diffusion or reflection. Scattering is responsible for the blue color of the sky and the white appearance of clouds.
What else can I help you with?
If a dark field condenser causes all light rays to bypass the objective where does the light come from that makes an object visible in a dark field?
In dark field microscopy, the light that reaches the objective only comes from light rays that are scattered by the object being observed. These scattered rays are then captured by the objective lens, illuminating the object against a dark background. The dark field condenser blocks the direct light rays that would otherwise create a bright background, allowing only the scattered light to form the image.
What happens when parallel rays of light hit a rough or bumpy surface?
When parallel rays of light hit a rough or bumpy surface, they get scattered in different directions due to reflection. This phenomenon is known as diffuse reflection. The surface roughness causes the light to reflect unevenly, leading to the diffusion of light in various directions.
What happened to light ray as they hit a rough surface?
When light rays hit a rough surface, they are scattered in many directions due to the uneven surface of the object. This phenomenon is known as diffuse reflection, where light rays reflect off the surface in a random manner. This is why we are not able to see a clear image in a rough surface compared to a smooth surface.
What is the scattering of light rays called?
The scattering of light rays is called "diffusion." This occurs when light rays are scattered in many different directions as they interact with particles or substances in the medium through which they pass.
When light rays hit a rough surface and bounce back at different angles?
Light will be both absorbed and will be reflected unevenly (scattered) when impinging on a surface that is irregular. It depends on the light and the surface, but some light will be absorbed, and the rest (a little or a lot) will be scattered when it is reflected in different directions.
When light rays hit a smooth surfer the rays are scattered?
A shadow is formed.
Why is he sky blue in he midle of he day?
The phenomenon is called Rayleigh scattering. White light from the Sun is scattered going through the atmosphere. The Sun's rays coming pretty much straight down aren't scattered much, but rays going sideways through the atmosphere - the sunrise and sunset rays - are scattered. Red light is scattered least, so those sunset rays make it through to make the sky appear red, while blue rays are scattered more. The blue light rays are scattered toward the ground, and this makes the sky appear blue.

What do you see when parallel rays of light it a bumpy surface you see?
You see the reflected light being scattered in different directions.

Why are the soap and detergent micelles scatter light rays?
Soap and detergent micelles scatter light rays because their structure involves a spherical arrangement of molecules with a different refractive index from the surrounding medium. This causes light to be scattered in different directions as it interacts with the particles in the micelles, resulting in the scattering of light rays.

What is it called when light rays hit a rough surface and bounce back at different angles?
It is called diffuse reflection when light rays hit a rough surface and bounce back at different angles. This creates a scattered reflection rather than a clear, single reflection.
Why clear sky appear blue?
sun's rays are made up of a mixture of seven colors. it is apparent in the rainbow. oxygen and nitrogen occupy not less than 98% of the gases in the air. blue light in the sun's rays are scattered when it hits those gases.
What does it mean when light is scattered?
Light is scattered when it bounces off particles or rough surfaces in different directions. This scattering can cause the light to disperse in various ways, affecting visibility or creating phenomena like rainbows.
