Transparent

The transcript discusses how different substances allow radiation to pass through them, noting that transparency can vary across different wavelengths. It highlights that while our atmosphere is clear to visible light, it blocks most ultraviolet and some infrared radiation. Additionally, it explains that fog is more transparent to certain infrared wavelengths than to visible light.

What does it mean for a substance to be transparent in one wavelength but not in another?

Can you explain the relationship between wavelength and transparency in different substances?

How does our atmosphere interact with visible light and ultraviolet radiation?

What types of radiation are blocked by our atmosphere?

In what way does fog differ in transparency to infrared wavelengths compared to visible light?
