1. How have our ideas about the solar system changed over time? 2. How do we use waves to ﬁnd out about the solar system? 3. How did Gallileo's observations of Jupiter provide evidence for th e heliocentric model of the solar system? 4. Compare the m

1. People used to believe that everything in the solar system orbite d the Earth (geocentric model) now we know that everything orbits the sun (heliocentric model). 2. Light, radio and micro-waves are used in telescopes to study the solar system and

1. How do you measure the focal length of a converging lens? 2. What do the eyepiece lens and the objective lens in a refracting telescope do? 3. What is refraction? HIGHER ONLY 4. Why does refraction occur?

1. Hold a lens near a window and focus the image of a distant objec t onto a piece of paper. Measure the distance between the lens and the paper. 2. Eyepiece lens: magniﬁes the image. Objective lens: refracts light to create the image. 3. The changin

1. What is reﬂection? 2. How do reﬂecting telescopes work? 3. What are the advantages of using reﬂecting telescopes rather th an refracting telescopes?

1. When light hits an object some of it bounces back oﬀ of it. 2. They have a large primary mirror which collects light from distan t objects and focus it to form a clear image. The eyepiece lens mag niﬁes this image. 3. To look at things that are ve

1. What do waves do? 2. What are the 2 types of wave and how are they diﬀerent? 3. Name and describe the 3 main features of waves. 4. How is wave speed calculated?

1. Transfer energy but not matter from one place to another. 2. Transverse waves move particles up and down but transfer ener gy at right angles to this movement. Longitudinal waves move parti cles backwards and forwards and transfer energy in the sa

1. What did William Herschel discover and how? 2. What did Johann Ritter discover and how?

1. Infrared waves by placing thermometers in light that had been s plit into its separatre colours by a prism and seeing the temperatur e change. One of the thermometers was placed beyond the red end of the spectrum and this one heated up the most. 2
