Next step. Get a green laser pointer. Yes, they are cheap too. Repeat the above experiment and what do you find? First, the light from the green laser is also just one color. Keep the green laser out.

A separate laser shines onto the album's surface itself so the other lasers always maintain a precise distance above the ... optical sensors detect the laser reflections from the grooves' walls.

Lasers have widespread applications as a light source in a variety of fields, including manufacturing, medicine, high-speed ...

This event follows a similar successful reflection from India's Chandrayaan-3 Vikram lander earlier. On May 24, 2024, Nasa's LRO transmitted a laser pulse to a small retroreflector aboard Jaxa's ...

Laser beam reflections between Earth and Moon 'a boost for science,' says NASA. 12 Aug 2020. Notable discoveries include that the Earth and Moon are slowly drifting apart – at “fingernail growth” rate ...

It was the first time a controlled laser mark test has been done on these animals in a wild setting and strengthens the evidence from other studies that monkeys don't recognise their own reflection.
