D. _____ has wavelengths between 0.7 and 0.4 millionths of a meter.
D1. What you see as different colors are electromagnetic waves of different ______.
D2. Red ligh has the _____ wavelengths (lowest frequency); blue light has the _____ wavelengths (highest frequency).
E. ______ is higher in frequency and has shorter wavelengths that visible light.
E2. Since ultraviolet radiation can kill cells, it is sometimes used to ____ equipment.
E3. The _____ in Earth's upper atmosphere helps protect the surface by absorbing much of the Sun's ultraviolet radiation.

E3. Ozone
Tell your little brother to read the assignment and make an effort.
He is not going to learn anything by having me or you do his homework for him
lol I have the same worksheet for homework right now and it is hard lol
D. The correct answer is "visible light."
D1. What you see as different colors are electromagnetic waves of different "wavelengths."
To understand how to get the answer, you can refer to the electromagnetic spectrum. The electromagnetic spectrum is a range of electromagnetic waves where each type of wave has a different wavelength and frequency. Visible light falls within a small portion of the electromagnetic spectrum.
D2. Red light has the "longest" wavelengths (lowest frequency); blue light has the "shortest" wavelengths (highest frequency).
To determine the order of colors in terms of wavelengths, you can refer to the visible light spectrum. Red light has the longest wavelength and lowest frequency, while blue light has the shortest wavelength and highest frequency.
E. The answer is "ultraviolet (UV) radiation."
E2. Since ultraviolet radiation can kill cells, it is sometimes used to "sterilize" equipment.
To understand how ultraviolet radiation is used, it is important to know that it has germicidal properties. Due to its ability to kill cells, UV radiation is sometimes used for sterilizing objects and equipment.
E3. The "ozone layer" in Earth's upper atmosphere helps protect the surface by absorbing much of the Sun's ultraviolet radiation.
To understand how the Earth is protected from UV radiation, you need to know about the ozone layer. The ozone layer is a part of the Earth's upper atmosphere that contains a high concentration of ozone molecules. It acts as a shield, absorbing a significant portion of the Sun's ultraviolet radiation before it reaches the Earth's surface.
