Which color of visible light has the shortest wavelength?

• Red

• Green

• Blue

• Violet

NGSS.HS-PS4-1

What happens to the frequency if the wavelength of light increases?

• Frequency increases

• Frequency decreases

• Frequency remains constant

• Frequency doubles

What is the formula for the speed of a wave?

• Speed of a wave = Wavelength + Frequency

• Speed of a wave = Wavelength / Frequency

• Speed of a wave = Wavelength x Frequency

• Speed of a wave = Frequency - Wavelength
