Second Quarter - First Summative Test in Science 10

For visible light, which property of visible electromagnetic waves changes with color?

• frequency and wavelength

• amplitude and frequency

• amplitude and light

• wavelength and sound

How do the wavelength, frequency and speed of ultraviolet rays in vacuum compare with those visible light? Wavelength Frequency Speed

• Longer Higher Slower

• Longer Lower Same

• Same Lower Slower

• Shorter Higher Same

A common property of all waves is the relationship between the speed (v), the wavelength (λ), and the frequency of the wave (f). The correct equation for this relationship is which of the following?

• v = f λ

• v = f/ λ

• f = v λ

• λ = vf

The diagram shows an electromagnetic spectrum: The electromagnetic spectrum shows the complete range of frequencies of electromagnetic waves from the lowest to the highest, including, in order, radio, infrared, visible light, ultraviolet, X-ray, and gamma ray waves. Which of the following statements explains how the electromagnetic waves are produced?

• Electromagnetic waves are produced when some kind of energy moves a substance, a material, or a “thing” within a medium that will conduct the mechanical energy of motion away from the source.

• Electromagnetic waves are longitudinal waves that are produced when the motion of the individual particles of the medium is in a direction that is parallel to the direction of energy transport.

• Electromagnetic waves are transverse waves that can be created by accelerating charges; moving charges back and forth will produce oscillating electric and magnetic fields, and this travel at the speed of light.

• Electromagnetic waves are produced whenever two waves of identical frequency interfere with one another while traveling opposite directions along the same medium.

Which description is TRUE about the radio waves in the electromagnetic spectrum?

• It has the shortest wavelength and highest frequency.

• It has the longest wavelength and lowest frequency.

• It has the longest wavelength and higher frequency.

• It has the wavelength and lower frequency.

In the visible spectrum, which color has the longest wavelength

• Blue

• Green

• Red

• Violet
