Answer:
The intensity of laser 2 is 4 times of the intensity of laser 1.
Explanation:
The intensity in terms of electric field is given by :
E is electric field
It means,
In this problem, lasers 1 and 2 emit light of the same color, and the electric field in the beam of laser 1 is twice as strong as the e-field of laser 2.
Let E is electric field in the beam of laser 1 and E' is the electric field in the beam of laser 2. So,
We have,
E'=2E
So,
So, the intensity of laser 2 is 4 times of the intensity of laser 1.
Answer:
Increases is the correct answer.
Explanation:
Just took the quiz.
Frequency refers to how often something happens. Period refers to the time it takes something to happen. Frequency is a rate quantity. Period is a time quantity. Frequency is the cycles/second
Answer:
thermal and radiant
Explanation:
- thermal energy refers to the energy transmitted through heat
- radiant energy refers to the energy transmitted through electromagnetic radiation, such as light
When the person lights the match, the match produces both heat (thermal energy) and light (radiant energy), so the correct answer is
thermal and radiant
Weight = (mass) x (gravity)
Divide each side by (gravity): Mass = (weight) / (gravity) =
(55.54 N) / (9.83 m/s²) =
5.65 kilograms
