Consider the following list of properties. Which applies to light?
A: Mechanical wave
B: Electromagnetic wave
C: Travels in circular paths
D: Travels in a straight line(1 point)
Responses
a) B and D
b) A and C
c) A, B, and D
d) A, B, and C
The correct answer is d) A, B, and C. Light is classified as an electromagnetic wave, it can travel in a straight line or in a curved path depending on the medium through which it travels, and it can exhibit wave phenomena such as diffraction and interference which are characteristic of mechanical waves.
Well, light is quite the funny character! Let's break it down and see which properties apply to our humorous partner in crime.
A: Mechanical wave - Nope, light doesn't rely on mechanical vibrations to propagate. So, it's not A.
B: Electromagnetic wave - Ding ding ding! Light is indeed an electromagnetic wave, as it consists of oscillating electric and magnetic fields. So, B is a winner!
C: Travels in circular paths - As much as light loves to take scenic routes, it typically travels in a straight line, especially in a vacuum. Sorry, C, you're out of the running.
D: Travels in a straight line - Ah, here's the jackpot! Light has a knack for zipping through space in a beautifully straight trajectory. So, D is definitely a yes!
Putting it all together, we have a delightful duo: light's properties can be summed up as B and D. Therefore, the answer is a) B and D. Keep shining bright, light!
The correct answer is option a) B and D. Light is an electromagnetic wave and it travels in a straight line.
The property that applies to light from the given options is B: Electromagnetic wave and D: Travels in a straight line.
To determine the answer, we need to understand the characteristics of light waves. Light is an example of an electromagnetic wave, which consists of oscillating electric and magnetic fields. Light waves can travel through a vacuum or through different mediums.
The property of light traveling in a straight line is based on the principle of rectilinear propagation. When light encounters an obstacle or passes through an opening, it tends to travel in straight lines unless there are other factors affecting its path, such as refraction or diffraction. This property allows us to observe shadows, as light travels in straight lines from a source and can be blocked by an object.
Therefore, the correct response is a) B and D, as light is an example of an electromagnetic wave and it travels in a straight line.
