After watching the video, what types of Electromagnetic Radiation do you use or encounter in your every day life?
Which type of electromagnetic radiation has the lowest energy?
Which type of electromagnetic radiation has the highest energy?
What does wavelength measure? Draw a picture if that helps you answer the question.
What does frequency measure? Draw a picture if that helps you answer the question.
Describe the relationship between the energy and wavelength of electromagnetic radiation.
Describe the relationship between the energy and frequency of electromagnetic radiation.
What color of visible light has the highest energy? What can you say about the frequency and wavelength of this light?
What color of visible light has the lowest energy? What can you say about the frequency and wavelength of this light?
If an object in the universe is not moving, predict what will happen to the wavelength and frequency of light that we see here on earth.
If an object in the universe is moving away from us, predict what will happen to the wavelength and frequency of light that we see here on earth. Hint: Would the light waves shift towards the red or blue side of the visible spectrum?
If an object in the universe is towards us, predict what will happen to the wavelength of light that we see here on earth. Hint: Would the light waves shift towards the red or blue side of the visible spectrum?
According to the Big Bang Theory, the universe is constantly expanding. Predict if light waves coming from a distant object would shift towards the red or blue side of the visible spectrum if the universe was expanding, that is objects were moving away from us.
What is redshift?
Explain how the Doppler Effect and redshift provide evidence to support the Big Bang Theory.
