Answer:

1. The type of interference happening when intersecting light waves subtract from each other to create dark spots is known as destructive interference

Destructive interference happens when the positive displacement or crest of one wave is cancelled by the negative displacement, or through of another wave of the same frequency resulting in a wave with lower amplitude

The letter on the diagram that shows destructive interference is the letter "c"

2. When particles pass translate through a key hole, they do not interfere with each. Therefore, when light is considered as a stream of particles, when it passes through a keyhole, there will be no  interference, and the light will particles will not interact with other light particles such that the pattern formed on on a wall on the other where the particles impinge on will be the shape of the single slit or keyhole

3. Three behaviors of light that support the theory that light travels in waves includes;

a) Refraction

b) Interference

c) Diffraction

Refraction

Refraction describes the change in velocity of light when it travels from one medium to another of different density, in which the light changes its speed

Interference

Interference is the superposition of two or more waves with the addition of the wave displacements resulting in a wave of larger or lesser amplitude than each of the individual waves

Diffraction

Diffraction is defined as the tendency of light to bend or spread when it goes past an object placed in its path by passing around the objects edge

4. The properties of a blackbody radiator includes;

1) A blackbody radiator absorbs all electromagnetic radiation incident on it

2) A blackbody radiator is capable of emitting black-body radiation

3) The peak of the emitted radiation depends on the blackbody temperature

4) The length of the wavelength of the peak radiation is inversely proportional to the temperature of the blackbody

5) The blackbody has zero coefficient of reflection or transmission and therefore, it does not reflect incident heat or light which makes it black

An example of a blackbody radiator is a burglar alarm that flashes light when there is an incident but cannot be ordinarily seen because of its dark color which is meant to absorb all incoming light

Explanation:

Wave interference is the phenomenon which describes the effect of the coming together or superposition of two or more waves to result in a wave displacement at a given point that is either reinforced (larger), cancelled (lower) amplitudes or the waves may have their original amplitudes when there is no interference

The wave displacement for the waves coming from the same source are taken as vectors from which the combination is calculated by using vector addition.

Comparing sound waves with different frequencies and wavelengths traveling through air,
aleksklad [387]

Explanation:

The speed of sound wave only depends on the property of the medium like density and the bulk modulus of the medium particle. The speed of sound also depends on the temperature of the medium.

On comparing sound waves with different frequencies and wavelengths traveling through air, the speed of the wave doesn’t depend on the frequency or the wavelength. Hence, the correct option is (1).

The motion of a car on a position time graph is represented with a horizontal tine What does this indicate about the car's motio
GalinKa [24]

Answer:

Position-Time graphs display the motion of a object by showing the changes of velocity with respect to time.

The motion of a car on a position-time graph that is represented with a horizontal line indicates that the car has stopped moving.

A straight line with a positive slope indicates that the car is moving at a constant velocity, and thus the slope is constant. On the other hand, a curve with a changing slope, shows that the velocity is changing.
