Why is the Sky Blue?

The sky appears blue due to a phenomenon called Rayleigh scattering. When sunlight enters Earth’s atmosphere, it collides with molecules and small particles in the air. Sunlight consists of many colors, each with different wavelengths. Blue light has a shorter wavelength and is scattered in all directions more than other colors (like red or yellow), which have longer wavelengths. This scattering causes the sky to look blue during the day.

Why Do We Need to Wear Safety Goggles During Science Experiments?

Wearing safety goggles during science experiments is crucial for several reasons:

Eye Protection: Experiments often involve chemicals, glassware, or projectiles that can pose a risk to the eyes. Goggles provide a barrier against splashes and flying debris.

Preventing Chemical Exposure: Many substances can irritate or damage the eyes. Goggles help prevent direct contact.

Enhanced Visibility: Safety goggles can also protect against bright lights or intense reactions that could impair vision.

Compliance with Safety Standards: Many educational institutions and laboratories require goggles as part of standard safety protocols to ensure everyone’s safety.

Using safety goggles helps prevent injuries and ensures a safer learning environment.
