What else can I help you with?
The dimming of starlight as it passes through the interstellar medium is called?
interstellar extinction. This phenomenon occurs due to the absorption and scattering of light by dust and gas particles present in the interstellar medium, leading to a decrease in the observed brightness of the starlight.
How will you determine a colloid?
Shine a light through it. If there are particles scattered, then it's a colloid
In liquid XYZ you notice that light is scattered as it passes through There is no precipitant in the bottom of the beaker though it has been sitting for several days This liquid must be a?
The liquid XYZ is likely a colloid. Colloids consist of tiny particles that are evenly dispersed throughout the liquid, causing the light to scatter as it passes through. The particles are small enough to remain suspended in the liquid and do not settle to the bottom, explaining the absence of a precipitant.
The Tyndall effect is the scattering of light by the particles in a what?
The Tyndall effect is the scattering of light by the particles in a colloid or fine suspension. This effect causes the beam of light to become visible as it passes through the colloidal mixture or suspension due to the reflection and dispersion of light by the particles.
What property is a mineral said to have when a person is able to view double images through it?
A mineral is said to have the property of "double refraction" or "birefringence" when a person is able to view double images through it. This occurs because the mineral has different refractive indices in different crystallographic directions, causing light to split into two rays as it passes through. This optical phenomenon can be observed in certain minerals, such as calcite, where objects viewed through the mineral appear doubled.
What test can be use to differentiate solution and colloid?
One way to differentiate between a solution and a colloid is through the Tyndall effect. In a solution, light passes through without scattering, while in a colloid, light scatters because the particles are large enough to reflect light. This can be observed by shining a light through the mixture - if the light beam is visible, it is a colloid, whereas if the beam is not visible, it is a solution.
Can you see diffraction in water?
Yes, diffraction can be observed in water. When light passes through water, it can be diffracted or bent as it encounters obstacles or changes in density within the water. This phenomenon is similar to diffraction observed with light passing through air or other media.
Is a beam of light visible as it passes through a colloid?
No, a beam of light is not visible as it passes through a colloid because the particles in the colloid are small and do not scatter light significantly, unlike in a suspension where the particles are bigger. This lack of scattering prevents the beam of light from being visible.
What is the name of the phenomenon that occurs when light is bent as it passes through different mediums?
The name of the phenomenon is refraction.
How does colloid move through the bloodstream?
Colloid silver first passes into the stomach, most of it will continue on that path out of the body. Some is absorbed into the blood stream though and able to pass with-out issue.

Some of the RF signal is reflected and some passes through an object but is redirected What is the phenomenon known as?
Refraction
Some of the RF signal is reflected and some passes through an object but is redirected What is this phenomenon known as?
Refraction
When a ray passes through a prism?
When a ray of light passes through a prism, it undergoes refraction, causing it to bend and split into its component colors due to differences in wavelengths. This phenomenon is known as dispersion.
Can light be diffracted?
Yes, light can be diffracted. Diffraction refers to the bending of light waves when they encounter an obstacle or slit that is similar in size to the wavelength of light. This phenomenon is commonly observed when light passes through small openings, resulting in interference patterns.
What is the tyndall effect used to distinguish between?
The Tyndall effect is used to distinguish between a solution and a colloid. In a solution, light passes through without scattering, while in a colloid, the dispersed particles cause light to scatter, making the beam visible.
