1. State an equation that links wave speed, distance and time.
\n2. Calculate the missing values in the table below.<\/p>\n

\"\"<\/a>3.<\/strong>\u00a0\u00a0 A wave travels at 1\u00b75 m.s-1<\/sup>. Calculate the time it will take to travel 30 m.<\/p>\n

4.<\/strong>\u00a0\u00a0 Very high waves produced in the ocean due to earthquakes are called tsunamis. A tsunami travelled from Sumatra to Somalia, a distance of 6000 km, in 7 hours. Calculate the speed of this wave in metres per second.<\/p>\n

5.<\/strong>\u00a0\u00a0 How long would it take a sound wave to travel from one end of a football pitch to the other if it is 105 m long? (Speed of sound in air is 340 m.s-1<\/sup>).<\/p>\n

6.<\/strong>\u00a0\u00a0 A surfer rides along the crest of a wave for a distance of 48 m in 12 s. Calculate their speed.<\/p>\n

7.<\/strong>\u00a0\u00a0 Light travels through space at 3\u00a0X 108<\/sup>\u00a0m .<\/p>\n

(a<\/em>)\u00a0\u00a0 The moon is 3\u00b78 X 108<\/sup> m from Earth. Calculate the time it will take for light reflected from the moon to reach Earth.<\/p>\n

(b<\/em>)\u00a0\u00a0 The Sun is an average of is 1\u00b75 X 1011<\/sup>\u00a0m from the Earth. Calculate the time it will take for light from the Sun to reach Earth.<\/p>\n","protected":false},"excerpt":{"rendered":"
