P6 Waves - The Electromagnetic Spectrum

What is the Electromagnetic Spectrum?

• The range of wavelengths and frequencies of the electromagnetic spectrum.
• The range of wavelengths and amplitudes of the electromagnetic spectrum.
• The range of frequencies and amplitudes of the electromagnetic spectrum.

Put these even groups of the EM spectrum in the correct order?

• Radio, Microwave, Infrared, Visible Light, Ultraviolet, X-rays, Gamma Rays
• Radio, Infrared, Microwave, Visible Light, X-rays, Ultraviolet, Gamma Rays
• Microwave, Radio, Infrared, Visible Light, Ultraviolet, X-rays, Gamma Rays
• Radio, Microwave, Infrared, Visible Light, Ultraviolet, Gamma Rays, X-rays

Which of these EM waves have the lowest frequency

• Radio
• Microwave,
• Infrared,
• Visible Light

Which of these EM waves have the highest frequency

• Ultraviolet
• Microwave
• X-ray
• Gamma rays

Which is the only group of the EM spectruym that human eyes can detect

(a)  

What colour of visible light has the longest wavelength and the lowest frequency

• red
• orange
• yellow
• green
• blue

What colour of visible light has the shortest wavelength and the highest frequency

• violet
• red
• orange
• yellow
• green

How are gamma rays created?

• By changes in an atoms nucleus
• By electrons being discharged from atoms

How are radio waves produced?

• By electrons oscillating in an electrical circuit.
• By metal ions oscillating in an electrical circuit.

What happens when an electric circuit absorbs radio waves?

• It causes electrons in the circuit to oscillate causing an alternating current in the circuit that has the SAME frequency as the radio wave.
• It causes electrons in the circuit to oscillate causing an alternating current in the circuit that has a DIFFERENT frequency as the radio wave.
