1. Which of the following statements about mechanical waves is true?
a. mechanical waves require a medium to travel through
b. mechanical waves do not have amplitude and wavelength
c. mechanical waves do not have frequency
d. mechanical waves can travel through blank space
2. Which waves have the shortest wavelength and highest energy on electromagnetic spectrum?
a. microwaves
b. x-rays
c. infrared
c. gamma rays
My answers are b and d
so is he right or wrong???
I think wrong...
To find the correct answers to these questions, let's break them down and explain how to determine the correct options:
1. Which of the following statements about mechanical waves is true?
a. mechanical waves require a medium to travel through
b. mechanical waves do not have amplitude and wavelength
c. mechanical waves do not have frequency
d. mechanical waves can travel through blank space
To determine the correct option, we need to understand the characteristics of mechanical waves. Mechanical waves are waves that require a medium (such as air, water, or solids) to travel through. Examples of mechanical waves include sound waves and seismic waves. As we know, sound requires a medium to travel from one place to another. Therefore, the correct answer is option a.
2. Which waves have the shortest wavelength and highest energy on the electromagnetic spectrum?
a. microwaves
b. x-rays
c. infrared
d. gamma rays
The electromagnetic spectrum consists of a range of electromagnetic waves of varying wavelengths and energies. To determine the correct option, we need to understand the order of the waves on the electromagnetic spectrum. From longest to shortest wavelength, the order is radio waves, microwaves, infrared, visible light, ultraviolet, x-rays, and gamma rays.
As we can see, gamma rays have the shortest wavelength and highest energy on the electromagnetic spectrum. Therefore, the correct answer is option d.
In conclusion, the correct answers to the given questions are:
1. a. mechanical waves require a medium to travel through.
2. d. gamma rays.
there right
b and gamma rays.
All are correct
This is the Google Forms Lesson 3, Quiz.
1. A [ mechanical waves require a medium to travel through]
2. D [gamma rays]
3. D [Infrared have lower frequency than X-rays]
4. B [2 Hz]
5. D [parallel (same direction)]
6. A [it is refracted]
7. C [1-crest, 2-trough]
8. C [gases]
9. B [they will be absorbed]
10. D [lowest pitch- Wave 2, highest frequency - Wave 1]
I hope this helps. Enjoy your day! :)
