Explanation:

TRUE OR FALSE
1. TRUE OR FALSE: The higher the frequency, the closer the waves are together and the LOWER the energy carried by the waves will be.
2. TRUE OR FALSE: The greater the force that produces a wave, the greater the amplitude of the wave and the greater the energy carried by the wave.
3. TRUE OR FALSE: In a transverse wave the higher the wave, the LOWER the amplitude
4. Wavelength is a measure of the distance from the crest on one wave to the crest on the very next wave.
5. TRUE OR FALSE: Speed is a measure of the distance a wave travels in an amount of time
6. TRUE OR FALSE: As a wave enters a different medium, the wave’s speed changes. Waves travel at different speeds in different media
7. TRUE OR FALSE: The highest point of a transverse wave is the crest and the lowest point is called a trough.

1 . The higher the frequency, the closer the waves are together and the LOWER the energy carried by the waves will be. FALSE

2. The greater the force that produces a wave, the greater the amplitude of the wave and the greater the energy carried by the wave. TRUE

3. In a transverse wave the higher the wave, the LOWER the amplitude FALSE

4.Wavelength is a measure of the distance from the crest on one wave to the crest on the very next wave, TRUE
5. Speed is a measure of the distance a wave travels in an amount of time TRUE

6. As a wave enters a different medium, the wave’s speed changes. Waves travel at different speeds in different media TRUE

7. The highest point of a transverse wave is the crest and the lowest point is called a trough. TRUE

What is Wave ?

A wave is a disturbance in a medium that carries energy and as well as momentum. Energy can be transferred in the form of wave in the medium. there are two types of wave,

longitudinal wave : in which, vibration of the medium (particle) is parallel to propagation of the wave as shown in the fig.1. Sound wave is a longitudinal wave.

Transverse wave : in which, vibration of the medium (particle) is perpendicular to propagation of the wave as shown in the fig.2. Light wave is a longitudinal wave.

1. E = hυ where υ is a frequency which shows direct relation between Energy E and frequency υ. Hence it is false.

2. True

3. In a transverse wave the higher the crest in the wave, the higher the amplitude. FALSE

4. True

5. True, Speed = Distance÷Time

6. due to change in refractive index, velocity changes TRUE

7.True

Why is it important for body cell to have twice and many chromosomes as sex cells?

Answers

Answer:

Why sex cells only need half the number of chromosomes compared to other cells in the body? As gametes are produced, the number of chromosomes must be reduced by half. Why? The zygote must contain genetic information from the mother and from the father, so the gametes must contain half of the chromosomes found in normal body cells.
