Questions with solutions
Q1 — Transparent, Translucent & Opaque · easy · theory
An object through which you can see clearly is called:
A. transparent ✓ Correct
B. opaque
C. translucent
D. luminous
Solution: Transparent objects let almost all light pass straight through, so you can see clearly through them, like clear glass.
Q2 — Transparent, Translucent & Opaque · easy · theory
Which of these is a transparent object?
A. A brick wall
B. A metal sheet
C. A wooden door
D. A clear glass window ✓ Correct
Solution: A clear glass window lets light pass through and you can see through it, so it is transparent. The others block light and are opaque.
Q3 — Transparent, Translucent & Opaque · easy · theory
An object that does not allow any light to pass through it is called:
A. transparent
B. shiny
C. opaque ✓ Correct
D. translucent
Solution: Opaque objects block light completely, so you cannot see through them at all, like a wall or a wooden board.
Q4 — Transparent, Translucent & Opaque · easy · theory
Which of these is an opaque object?
A. Clear water
B. A wooden board ✓ Correct
C. A glass tumbler
D. A sheet of cellophane
Solution: A wooden board stops light completely, so it is opaque. Clear water, a glass tumbler and cellophane let light through.
Q5 — Transparent, Translucent & Opaque · medium · theory
Butter paper and frosted glass let some light through but you cannot see clearly through them. They are:
A. opaque
B. transparent
C. luminous
D. translucent ✓ Correct
Solution: Translucent objects let only some light pass and scatter it, so you see a blurry, unclear view through them.
Q6 — Transparent, Translucent & Opaque · medium · theory
Which pair correctly matches the object with its type?
A. Wooden door – transparent
B. Clear glass – opaque
C. Tracing paper – translucent ✓ Correct
D. Brick wall – transparent
Solution: Tracing paper lets some light through but blurs the view, so it is translucent. Clear glass is transparent, while a wooden door and a brick wall are opaque.
Q7 — Transparent, Translucent & Opaque · medium · theory
Through which object can you make out the shape of your friend but not see them clearly?
A. Clear window glass
B. A steel plate
C. A thick book
D. Frosted (ground) glass ✓ Correct
Solution: Frosted glass is translucent. It scatters the light, so you can see a fuzzy shape but not clear details.
Q8 — Transparent, Translucent & Opaque · medium · theory
Why can you not see clearly through a translucent sheet?
A. It blocks all the light
B. It lets only some light pass and scatters it ✓ Correct
C. It gives out its own light
D. It is always coloured black
Solution: A translucent sheet allows only part of the light through and scatters it in different directions, so the view is blurred.
Q9 — Transparent, Translucent & Opaque · hard · theory
Which object would cast the darkest, sharpest shadow, because it blocks light completely?
A. Clear glass
B. Oiled paper
C. A wooden plank ✓ Correct
D. Frosted glass
Solution: A dark, sharp shadow needs an opaque object that stops all the light. A wooden plank is opaque; the others let some light through and give faint shadows.
Q10 — Transparent, Translucent & Opaque · hard · theory
When a few drops of oil fall on ordinary paper, that spot becomes more see-through and lets more light pass. That oily spot:
A. becomes more transparent ✓ Correct
B. starts giving out its own light
C. turns into a mirror
D. becomes more opaque
Solution: The oil fills the tiny gaps in the paper so more light can pass straight through. The spot lets light through better, becoming more transparent.
