What is the effect of sunlight on special ink that is only visible in sunlight?

Back

Sunlight can provide energy to the ink, making it visible.

Front

Which type of light is more likely to damage materials: X-ray or gamma ray?

Back

Neither X-ray nor gamma ray light is likely to damage the material because the material does not take in energy from either type.
