Question

the passage explains that different colors of light have different wavelengths. if a camera lens does not focus all wavelengths correctly, what problem mentioned in the passage is most likely to happen to a photo?

○ the photo will show a perfect rainbow in every shot.

○ the photo will always appear darker than the scene.

○ the camera will convert light into sound.

○ colors may appear blurred or not sharp because rays of different colors do not meet properly on the sensor.

Explanation:

1. Analyze Option A: A perfect rainbow in every shot is not a typical result of lens focusing issues with different wavelengths, so A is incorrect.
2. Analyze Option B: A lens not focusing wavelengths correctly doesn't directly cause the photo to be darker; factors like exposure affect brightness, so B is incorrect.
3. Analyze Option C: Cameras don't convert light to sound; they capture light for images, so C is incorrect.
4. Analyze Option D: Different light wavelengths (colors) not focusing properly on the sensor would lead to blurred or unsharp colors, which matches the physics of light and lens focusing, so D is correct.

Answer:

D. Colors may appear blurred or not sharp because rays of different colors do not meet properly on the sensor.
