🔍 Key Concepts

• Relationship between radio waves and electromagnetic waves • The known speed of light in free space and its common units • How exam questions sometimes use unit conversions and combined choices (like 'All of the above')

💭 Think About

• Are all three numerical/wording statements talking about the same physical speed, just in different units or descriptions? • Does any one of the options contain a value or unit that is clearly inconsistent with the known speed of light in free space? • If one statement is clearly wrong, what does that imply about a choice like 'All of the above'?

✅ Before You Answer

• Recall or look up the standard value for the speed of light in free space in meters per second and in miles per second • Check whether radio frequency waves in free space travel at a different speed than light or are they part of the same electromagnetic spectrum • Verify whether each individual statement (A, B, C) is correct on its own before considering choice D
