How do you know if something is opaque?
The choice between opaque vs. translucent is clear: when something allows no light to pass through, it is opaque. When something allows some light to pass through, it is translucent. If it allows all light to pass through, it is transparent.
What is the opaque object?
An opaque object is something that allows no light through it. Concrete, wood, and metal are some examples of opaque materials. Some materials can be opaque to light, but not to other types of electromagnetic waves.
What is an example of an opaque material?
Materials that allow some light to pass through are called translucent and items that don’t allow any light to pass through are called opaque. Examples of opaque materials are wood, stone and metal.
What determines whether a material is transparent or opaque?
A material is said to be opaque if the light energy can’t pass from it. It is absorbed by the material. Whereas transparent materials are those materials from which the light energy can cross without any dispersion.
Which of the following is not opaque object?
Answer: The answer is b) frosted glass .
What makes a material opaque?
Light waves cause vibrations in surface atoms, which are either absorbed, transmitted or reflected. If the energy only causes vibrations in the surface before reflecting off the object, then the object appears opaque. Therefore, opacity is caused by the reflection of light waves.
What determines whether a material is transparent or opaque quizlet?
What determines whether or not a material is transparent or opaque? The frequency of the light and the frequency of the object determine whether the object is opaque or transparent. Why are metals shiny in appearance? Metals re-emit light when free electrons vibrate instead of conserving the energy as interval energy.
Are all solid substances opaque?
Many solids are opaque, but some are transparent. Some dissolve in water, but some do not. These two substances illustrate the range of properties that solids can have.

What is an opaque material? An opaque object is something that allows no light through it. Concrete, wood, and metal are some examples of opaque materials. Some materials can be opaque to light, but not to other types of electromagnetic waves.
What is the difference between opaque objects and translucent objects?
Opaque objects are those that do not allow any light to pass through them. The book cover, brick, and other such solid things you can think of are all opaque in nature. This means that you cannot see through such an object. Translucent objects are those that come in between opaque and transparent materials. To understand translucent material,
How do you know if a view is opaque or opaque?
A Boolean value that determines whether the view is opaque. This property provides a hint to the drawing system as to how it should treat the view. If set to YES, the drawing system treats the view as fully opaque, which allows the drawing system to optimize some drawing operations and improve performance.
What is the expected alpha value of an opaque view?
An opaque view is expected to fill its bounds with entirely opaque content—that is, the content should have an alpha value of 1.0. If the view is opaque and either does not fill its bounds or contains wholly or partially transparent content, the results are unpredictable.
