Answer:
Newton's corpuscular theory stated that light consisted of particles that travelled in straight lines. Huygens argued that if light were made of particles, when light beams crossed, the particles would collide and cancel each other. He proposed that light was a wave.
Answer:
given to you by others
Explanation:
Since it is other people who are giving you the feedback they may notice things that you are not aware you are doing. they can also give /help you to alter that thing and help you achieve you goal
Answer:
Explanation:
According to Newton's second law, we have:
The force of friction is opposite to the motion of the block.
Using the following kinematic equation, we can calculate the distance traveled by the block before it stops().
Solving for x and replacing a from (1):
Answer:
λ = 11.29 x 10⁻⁷ m = 1129 nm
Explanation:
According to the law of conservation of energy:
where,
λ = maximum wavelength = ?
h = Plank's Constant = 6.625 x 10⁻³⁴ J.s
c = speed of light = 3 x 10⁸ m/s
e = charge on electron = 1.6 x 10⁻¹⁹ C
V = stopping poteential = 1.1 V
Therefore,
<u>λ = 11.29 x 10⁻⁷ m = 1129 nm</u>
