Based on your knowledge of the electromagnetic spectrum, why are radio waves considered harmless while ultraviolet waves and x-rays considered harmful?
Radio waves have longer wavelengths, lower frequency, and lower energy than ultraviolet waves and x-rays.
Lower energy and higher frequency ultraviolet waves and x-rays is enough to break bonds and damage cells.
High frequency and energy of radio waves mean that they penetrate much farther through matter than uv or x-rays.
The energy of the lower frequency ultraviolet waves and x-rays is high enough to be considered ionizing radiation.
Why does light behave as shown in the image when it passes from air to glass?
Light is scattered on the surface of the glass.
Light slows down when it passes into a denser medium.
Light is partially reflected on the surface of the glass.
Light splits into its constituent colors when it passes through glass.
