EM Spectrum, Double Slit, Reflection

Which type of wave has the most energy?

• Radio waves

• Red, visible light

• Ultraviolet

• Gamma Rays

Which type of wave has the longest wavelength?

• Radio waves

• Red, visible light

• Ultraviolet

• Gamma Rays

Which type of wave travels fastest in a vacuum?

• Microwave

• Gamma Rays

• Visible Light

• All the same

Light travels through a vacuum for five minutes. Which equation would you use to determine how far the light traveled?

• 
• 
• 
• Any of the equations will solve for distance

A radiowave has a wavelength of 3m. Which equation would you use to determine the frequency of the wave?

• 
• 
• 
• Any of the equations will solve for frequency

The red light bends as it travels through each of the tiny slits in the card. Which wave behavior is this?

• Reflection

• Refraction

• Diffraction

• Interference

The light from one slit interacts with light from the other slit, forming patterns of bright and dark spots. Which wave behavior is this?

• Reflection

• Refraction

• Diffraction

• Interference

If the light were infrared instead of red, the wavelength would be larger. How would this change the spacing of dots?

• y decreases - dots are closer together

• y increases - dots are farther apart

• y is constant - dots stays equally spaced

• y is zero - there is only one dot

If the two slits were farther apart, how would this change the spacing of dots?

• y decreases - dots are closer together

• y increases - dots are farther apart

• y is constant - dots stays equally spaced

• y is zero - there is only one dot

If this were bright, white light instead of monochromatic red, how would this change the pattern?

• y decreases - dots are closer together

• y increases - dots are farther apart

• There would rainbows as the white light breaks up.

• There would be only two spots but of white light.
