Light Waves and EM Waves

A pencil standing half in and half out of water looks bent because of:

• Interference

• Reflection

• Diffraction

• Refraction

Wave that do not require a medium are called...

• Electromagnetic wave

• Transverse wave

• sound wave

• Compression wave

When two or more waves combine to form a single wave, it is called.....

• wavelength

• Interference

• standing wave

• frequency

constructive interference occurs when two waves:

• add up to create a wave that is smaller than either single wave.

• add up to create a wave that is larger than either single wave.

• are moving at the same speed.

• have equal and opposite amplitudes.

Diffraction causes waves to:

• bounce off hard surface.

• spread out through small openings.

• become smaller as they move.

• increase their frequency.

why does an apple look red?

• It reflects red light.

• It absorbs red light.

• It reflects green and blue light,

• It reflects all colors of light except red.
