Questions with solutions
Q1 — Luminous & Non-luminous Objects · easy · theory
Which of the following is a luminous object?
A. A wooden table
B. A mirror
C. The Sun ✓ Correct
D. The Moon
Solution: A luminous object gives out its own light. The Sun makes its own light. The Moon, a table and a mirror only reflect light that falls on them.
Q2 — Luminous & Non-luminous Objects · easy · theory
A non-luminous object is one that:
A. is always hot
B. does not give out its own light ✓ Correct
C. is always shiny
D. gives out its own light
Solution: Non-luminous objects do not produce their own light. We see them only because they reflect light coming from a luminous source.
Q3 — Luminous & Non-luminous Objects · easy · theory
Which of these is a non-luminous object?
A. The Sun
B. The Moon ✓ Correct
C. A burning candle
D. A glowing electric bulb
Solution: The Moon does not make its own light; it shines by reflecting sunlight. A candle flame, a glowing bulb and the Sun all give out their own light.
Q4 — Luminous & Non-luminous Objects · easy · theory
Objects that give out their own light are called:
A. transparent objects
B. non-luminous objects
C. luminous objects ✓ Correct
D. opaque objects
Solution: Objects that produce their own light, such as the Sun, a flame or a lit bulb, are called luminous objects.
Q5 — Luminous & Non-luminous Objects · medium · theory
The Moon appears bright in the night sky because it:
A. is a burning star
B. is very hot
C. makes its own light
D. reflects light from the Sun ✓ Correct
Solution: The Moon is non-luminous. It looks bright only because it reflects the sunlight that falls on it towards the Earth.
Q6 — Luminous & Non-luminous Objects · medium · theory
Which group contains only luminous objects?
A. Sun, Moon, star
B. Moon, mirror, book
C. candle flame, wall, chair
D. Sun, star, glowing bulb ✓ Correct
Solution: The Sun, a star and a glowing bulb all produce their own light. The other groups include non-luminous things like the Moon, a mirror, a book, a wall and a chair.
Q7 — Luminous & Non-luminous Objects · medium · theory
We are able to see a non-luminous object such as a chair only when:
A. it becomes very hot
B. it is completely dark
C. light falls on it and reflects into our eyes ✓ Correct
D. it starts glowing on its own
Solution: A chair has no light of its own. Light from a source falls on it, bounces off, and enters our eyes, letting us see it.
Q8 — Luminous & Non-luminous Objects · medium · theory
Which of these is a luminous object?
A. A steel plate
B. A firefly ✓ Correct
C. A wooden log
D. A pebble
Solution: A firefly is a living thing that produces its own light, so it is luminous. A log, a plate and a pebble only reflect light.
Q9 — Luminous & Non-luminous Objects · hard · theory
A polished steel spoon shines brightly in sunlight. Is the spoon luminous or non-luminous?
A. Luminous, because it is made of metal
B. Luminous, because it shines
C. Non-luminous, because it only reflects light ✓ Correct
D. Non-luminous, because it feels cold
Solution: Shining is not the same as making light. The spoon has no light of its own; it only reflects sunlight, so it is non-luminous.
Q10 — Luminous & Non-luminous Objects · hard · theory
In a room that is completely dark with no light source, you cannot see a red apple on the table. Why?
A. The apple is luminous only in daytime
B. The apple stops existing in the dark
C. The apple turns black in the dark
D. There is no light for the apple to reflect into your eyes ✓ Correct
Solution: The apple is non-luminous, so it can only be seen by reflecting light. With no light in the room, nothing reflects to your eyes, so you cannot see it.
