Question

You will need a piece of clear glass, a steel plate, a piece of thick paper, and a few drops of oil.

Hold up the clear glass and try to look at a lighted torch through it. You can see the light from the bulb through the glass because it lets the light through. It is transparent. What happens when you try to look at the torch through the steel plate? You cannot see the light because the steel plate does not let the light through. It is opaque.

What happens when you use the paper? Many types of paper will allow some light through. They are translucent. If your paper is opaque, rub a few drops of oil on it and check again.

In this list of items, circle the ones that are transparent and underline those that are opaque.

glass tumbler, steel plate, aluminum foil, soap, and plasticine.

Is a mirror transparent, translucent, or opaque?

Answer 1

From the list the transparent and opaque objects are-

• The property in which the light passes through a medium is known as a transparent property.
• The medium that allows light to pass through it is known as a transparent medium.
• The medium that allows only a fraction of light to pass through them is known as a translucent medium.
• Objects that don’t allow light to pass through them is known as opaque medium.
• Transparent: Glass tumbler.
• Opaque: Steel plate, aluminum foil, soap, plasticine.
• A mirror is an opaque object.
• A mirror is not transparent because it reflects the light that shines on it, allowing us to see our reflection.
• As a result, glass is transparent, whereas mirrors are opaque.
