In physics, the image that can be displayed on the light is called .

Real. Virtual image.

The first one didn't work.

1.Real. 2.Imaginary.

I'm the first to answer, give it points.

Summary. Light has the physical property of shining on a certain object to produce the corresponding (), the energy of the photon is () Therefore, the higher the () of the light, the greater the energy of the photon:

The first null: the photoelectric effect.

The second void: light energy.

The third null: frequency.

Light has the physical property of illuminating a certain object and causing the corresponding (), and the energy of the photon is () Therefore, the higher the () of the light, the greater the energy of the photon.

Light has the physical property of shining on a certain object to produce the corresponding (), and the energy of the photon is () Therefore, the higher the () of the light, the larger the energy liquid of the photon? I'm answering for you :

Light has the physical property of irradiating a certain object to produce the corresponding (), and the energy of the photon is () Therefore, the higher the () of the light, the greater the energy of the photon: the first void: the photoelectric effect, the first space: the second space: the light energy, the third space: the frequency suspect.

If you have any other questions, then you can just ask me, please give me a like! Thank you! I wish you all the best! Academic success.

Light is an electromagnetic wave (visible spectrum) that can be seen by the human eye. In the scientific definition, light sometimes refers to the entire spectrum of electromagnetic waves. Light is made up of a type of elementary particle called a photon.

It has particle and wave properties, or wave-particle duality. Light can travel in transparent substances such as vacuum, air, water, etc.

High School Physics Elective 3-4 mentions two definitions of light at the beginning of the chapter on "Light."

1.Maxwell believed that light is a kind of electromagnetic wave - emphasizing the fluctuating nature of light.

2.Albert Einstein believed that light is made up of countless photons – emphasizing the particle nature of light.

It is now theorized that light is both an electromagnetic wave and a particle (photons are different from ordinary particles).

Unaffected by space and time, it is an absolutely existing substance.

There is no exact definition, only the study of nature.

b [Analysis] Test question analysis: The reflection of a bird standing in the water belongs to the plane mirror image, which is the reflection of light, a false; The formation of shadows is the linear propagation of light, b pairs; The chopsticks inserted into the water appear to be bent due to the refraction of light, c wrong; The periscope is using the reflection of light, d wrong. Test Centers :

Straight line propagation of light. 1. Light propagates in a straight line in the same homogeneous medium, and in daily life, laser collimation, small hole imaging and shadow formation all indicate that light propagates in a straight line in the same medium. 2. When the light shines on the interface of the object, a part of it is reflected back and reflected like a celery elephant.

3. When light is obliquely emitted from one medium to another, the direction of propagation will be deflected and refraction will occur.
