1. light waves travel

1. the formula for wave speed is wave

speed =

wavelength.

Explanation:

Question 1:

To solve this, we recall the speeds of light and sound waves in air. Light waves (electromagnetic) travel much faster than sound waves (mechanical) in air. From the word bank, "faster" is the appropriate term as it compares the speeds (light > sound in air).

The formula for wave speed is a fundamental concept in physics (wave mechanics): \( v = f \lambda \), where \( v \) is wave speed, \( f \) is frequency, and \( \lambda \) is wavelength. So the missing term is "frequency" to complete \( \text{wave speed} = \text{frequency} \times \text{wavelength} \).

Answer:

faster
