What is Longer wavelengths (~620, 750 nm)?

Longer wavelengths are like the slow, lazy waves in a big ocean, they stretch out more and take their time to move.

Imagine you're on a beach, watching two different kinds of waves come toward you. One is short and quick, crashing right in front of you, while the other is tall and slow, rolling across the water for a long way before it reaches your feet. The longer wavelengths are like those slow, rolling waves, they’re measured in nanometers, which is a tiny unit of distance, about one billionth of a meter!

• 620 nm and 750 nm are the lengths of some of these slow waves.
• These kinds of waves are what we see as red light when they hit our eyes.
• Think of it like a slow, deep voice, it's not quick or bright, but it carries far and feels calm.

So next time you see something red, like a ripe apple or a fire truck, remember, it’s the long, lazy waves of light showing off! Longer wavelengths are like the slow, lazy waves in a big ocean, they stretch out more and take their time to move.
