Nature of Light Quick Check 1 of 51 of 5 Items Question What is the speed of light in a vacuum?(1 point) Responses v=3⋅108 m/s v equals 3 times 10 superscript 8 baseline m per s c=3⋅108 m/s c equals 3 times 10 superscript 8 baseline m per s c=2⋅108 m/s c equals 2 times 10 superscript 8 baseline m per s v=2⋅108 m/s

Answer 1

The speed of light in a vacuum is represented by the symbol \( c \) and is approximately \( c = 3 \times 10^8 \) m/s. Therefore, the correct response is:

**c = 3⋅10^8 m/s**
