Question 21 options:

Answer 1

Here are the answers to your questions:

Question 1

Answer: 5 m/s.
Explanation: The formula for wave speed is \( v = f \times \lambda \). With a frequency \( f = 2 \) Hz and wavelength \( \lambda = 10 \) m, the speed \( v = 2 , \text{Hz} \times 10 , \text{m} = 20 , \text{m/s} \).

Question 2

Answer: electromagnetic waves.
Explanation: Electromagnetic waves can travel in a vacuum, whereas mechanical waves require a medium.

Question 3

Answer: vacuum.
Explanation: Sound cannot travel in a vacuum, while light travels at 3.00 x 10^8 m/s in a vacuum.

Question 4

Answer: by the vibration of particles in a medium.
Explanation: Waves transfer energy through the oscillation and vibration of particles in a medium.

Question 5

Answer: surface wave.
Explanation: Surface waves are a combination of longitudinal and transverse waves.

Question 6

Answer: frequency.
Explanation: Frequency is defined as the number of waves produced in a given amount of time.

Question 7

Answer: Refraction occurs when light enters a new medium at an angle and it bends to change direction.
Explanation: This combines the concept of entering a new medium and changing direction, reflecting a more complete understanding.

Question 8

Answer: wavelength.
Explanation: The distance from any point on a wave to an identical point on the next wave is called the wavelength.

Question 9

Answer: decreases.
Explanation: As wavelength increases, frequency decreases, according to the wave relationship \( v = f \lambda \).

Question 10

Answer: The sun's rays reflect off the moon's surface.
Explanation: We see the moon at night because sunlight reflects off the moon's surface.

Question 11

Answer: height.
Explanation: The amplitude of a wave is related to the maximum height of the wave from its rest position.
