Two or more waves combining to produce a wave with a smaller displacement is called _____.

2 answers:

Answer:
Destructive interference

Explanation:
Interference is a term used to refer to the combination of two waves or their overlap
There are two types of interference:
1- Constructive interference: This happens when the waves overlap/combine to produce a resultant wave with a larger displacement
2- Destructive interference: This happens when the waves overlap/combine to produce a resultant wave with a smaller displacement

Hope this helps :)

Two or more waves combining to produce a wave with a smaller displacement is called Destructive interference.

Explanation:

The interference of 2 waves of equal frequency and opposite section, leading to their cancellation wherever the negative displacement of 1 perpetually coincides with the positive displacement of the opposite.

In harmful interference, the crest of 1 wave meets the trough of another, and therefore the result's a lower total amplitude.

Calculate the longest wavelength visible to the human eye. express the wavelength in nanometers to three significant figures.

slega [8]

NOTE: The given question is incomplete.

The complete question is given below.

The human eye contains a molecule called 11-cis-retinal that changes conformation when struck with light of sufficient energy. The change in conformation triggers a series of events that results in an electrical signal being sent to the brain. The minimum energy required to change the conformation of 11-cis-retinal within the eye is about 164 kJ/mole. Calculate the longest wavelength visible to the human eye.

Solution:

Energy (E) = 164 kJ/mole

E = 164 kJ/mole = 164 kJ /6.023 x 10²³

= 2.72 x 10⁻²² kJ = 2.72 x 10⁻¹⁹J

Planck's constant = 6.6 x 10⁻³⁴ J s,

Speed of light = 3.00 x 10⁸ m/s

Let the required wavelength be λ.

Formula Used: E = hc / λ

or, λ = hc / E

or, λ = (6.6 x 10⁻³⁴ J s)× (3.00 x 10⁸ m/s) / (2.72 x 10⁻¹⁹J)

or, λ = 7.28 x 10⁻⁷ m

or, λ = (7.28 x 10⁻⁷ m) ×( 1.0 x 10⁹ nm / 1.0 m)

or, λ = (7.28 x 10² nm)

or, λ = 728 nm

Hence, the required wavelength will be 728 nm.

The driver of a car traveling at a speed of 27 m/s slams on the brakes and comes to a stop in 3 s. If we assume that the speed c

NISA [10]

Answer:

Average speed = 13.5 m/s

Explanation:

Since the car is running at a speed of 27 m/s and it stops after 3 seconds by applying the brake. Therefore, the initial speed of the 27 m/s and final speed is 0.

Use below formula to find the average speed :

Average speed = (Initial speed + final speed ) / 2

Average speed = (27 + 0 ) / 2

Average speed = 13.5 m/s

Given f(x)=3x-11 which of the following is f(7) A. 10 B. 32 C. -6 D. 6

Crazy boy [7]

Answer:

The answer is A. 10

Explanation:

Given 

f(x) = 3x - 11

So, 

f(7) = 3 * 7 - 11

 = 21 - 11

 = 10
