What are some examples of EM waves

Physics
1 answer:
Alexxandr [17]3 years ago
5 0

Answer:

  • Microwaves
  • Heatwaves
  • Ultraviolent waves
  • WiFi signal
  • 4G/5G signals

Explanation:

All of these are examples of electromagnetic radiation or energy.

The spectra comprises most energy and matter we can account for so far.

The main distinction between EM waves and for example longitudinal acoustic waves is the medium of energy transfer (and rules). EMWs are subject to the idiosyncratic effects of Quantum Mechanics while other 'macro' waves whose medium relies on gross material, are apparently not.

wolverine [178]

Answer:

Stephen William Hawking

Explanation:

Stephen William Hawking was a popular theoretical physicist born on  8th January 1942.

He served as the professor of mathematics at the Cambridge university

He was director at the center for theoretical cosmology.

He has theorized that the black holes will emit radiations and the radiations is known by his name Hawking's radiation.

His book 'The Brief History of Time' appeared as one of the best seller according to the Sunday Times.

Hawking's was diagnosed for a rare disease named as motor neuron disease.

He received numerous awards and elected as the fellow of royal society.

He passed away on 14th March 2018.

You're driving down the highway late one night at 21 m/s when a deer steps onto the road 35 m in front of you. Your reaction tim
andreev551 [17]

Speed with which initially car is moving is 21 m/s

Reaction time = 0.50 s

distance traveled in the reaction time d = v t

d = 21 * 0.50 = 10.5 m

deceleration after this time = -10 m/s^2

now the distance traveled by the car after applying bakes

v_f^2 - v_i^2 = 2a d

0 - 21^2 = 2(-10)d

d = 22.05 m

so total distance moved before it stop

d = 22.05 + 10.5 = 32.55 m

so the distance from deer is 35 - 32.55 = 2.45 m

now to find the maximum speed with we can move we will assume that we will just touch the deer when we stop

so our distance after brakes are applied is d = 35 - 10.5 = 24.5 m

again by kinematics

v_f^2 - v_i^2 = 2 ad

0 - v^2 = 2(-10)(24.5)

v = 22.1 m/s

so maximum speed would be 22.1 m/s

(b) If the object is at 330 feet and its instantaneous velocity is 3 feet per minute at 30 minutes, what is the approximate posi
ELEN [110]

Answer:

The final position is 36 feet.

Explanation:

initial position, d = 330 feet

speed, v = 3 feet per minute

time, t = 30 minute

now the time is 32 minute

time interval = 2 minute

So, the distance in 2 minutes is

d' = 2 x 3 = 6 feet

So, the final position is

D = 30 + 6 = 36 feet
