Travel close to larger boats so they can more easily see you
Well, when you're out on the water in a smaller fishing boat, canoe, or kayak, it's important to stay visible to larger boats for safety. One extra precaution you can take is to use bright colors or reflective tape on your vessel, so you're easily spotted. Also, consider carrying a whistle or a flashlight to signal your presence, especially during low-light conditions. Just a little extra effort can go a long way in ensuring a safe and enjoyable time on the water.
Because they are smaller than the wavelengths of visible light.

Atoms are typically smaller in size than the wavelength of visible light, which makes them difficult to detect using visible light. Additionally, atoms do not absorb or reflect visible light in a way that allows them to be seen by the human eye. Special techniques such as electron microscopes are often used to visualize atoms.

A microscope is used to view smaller objects at a magnified scale, allowing for detailed observation of structures that are not visible to the naked eye.
No, atoms are too small to be directly observed with visible light as their size is much smaller than the wavelength of visible light. To see atoms, scientists use techniques such as electron microscopes or other sophisticated imaging methods that can detect them indirectly.
Visible light has a higher frequency, a higher energy per photon, and a smaller wavelength, compared to infrared.
Millimeters can be used as a measurement for items smaller than one centimeter
When the moon grows smaller, it is said to be waning. This is the period between the full moon and the new moon, when the visible portion of the moon decreases.
