What are translucent materials give two examples?

What are translucent materials give two examples?

Examples of transparent items are glass, water, and air. Those materials that allow some light to pass through them are called translucent and include things like frosted glass and wax paper. If an object does not allow any light to pass through it then it is opaque.

What is the difference between transparent and opaque objects give two examples of each?

Transparent objects are the objects which allow light to pass through them.Eg:glass,water etc,whearas opaque objects are the objects which do not light to pass through them. Example:wood,steel etc. Opaque : The substances which does not allow light to pass through it.

Can rocks be translucent?

Rocks can be transparent, translucent or opaque in nature. These properties depend on the amount of light being absorbed and passed through the rock and also the chemical structure of the rock. Translucent rocks admit light diffusely and hence are partially transparent.

Is Diamond transparent translucent or opaque?

Because of its high refrative index (2.5), diamond can reflect and refract light. Therefore, it is a transparent substance. Translucent substance permits the passage of light in such a way that an object cannot be seen clearly through the substance, e.g., frosted glass. Opaque substance does not permit light to pass.

What are two common minerals?

The feldspar-group, a very complex mixture of oxygen, silicon, aluminum and trace elements like sodium, potassium, calcium and more exotic elements like barium, are by far the most common minerals, making up almost 58% of all to a geologist accessible rocks, especially magmatic and metamorphic ones.

How do I know what minerals I have?

When identifying a mineral, you must:

1. Look at it closely on all visible sides to see how it reflects light.
2. Test its hardness.
3. Identify its cleavage or fracture.
4. Name its luster.
5. Evaluate any other physical properties necessary to determine the mineral’s identity.

How can you determine if one mineral is harder than the other?

Mohs hardness scale is used by geologists to compare the hardness of minerals only. The scale arranges a series of minerals in order of increasing relative hardness, from 1 to 10. Note that this is a relative hardness scale; diamond is actually over four hundred times harder than talc.
