How to approach this question
1. Remember that a red flower reflects red light and absorbs other colours.
2. A green filter only allows green light to pass through it (it absorbs other colours).
3. Consider the light that is reflected from the flower (red light) and whether it can pass through the green filter to reach the gardener's eye.
Full Answer
A.Black✓ Correct
Black
A red flower appears red because it reflects red light and absorbs all other colours. A green filter works by only allowing green light to pass through (transmitting it) and absorbing all other colours.
When the gardener looks at the red flower, the flower reflects red light towards the filter. However, the green filter absorbs red light. Therefore, no light from the flower passes through the filter to the gardener's eye. When no light reaches the eye from an object, it appears black.
Common mistakes
✗ Thinking the flower will look green because of the filter.\n✗ Thinking the flower will still look red because it is a red flower.
