Edited at 2024-01-28 09:45:27This Valentine's Day brand marketing handbook provides businesses with five practical models, covering everything from creating offline experiences to driving online engagement. Whether you're a shopping mall, restaurant, or online brand, you'll find a suitable strategy: each model includes clear objectives and industry-specific guidelines, helping brands transform traffic into real sales and lasting emotional connections during this romantic season.
This Valentine's Day map illustrates love through 30 romantic possibilities, from the vintage charm of "handwritten love letters" to the urban landscape of "rooftop sunsets," from the tactile experience of a "pottery workshop" to the leisurely moments of "wine tasting at a vineyard"—offering a unique sense of occasion for every couple. Whether it's cozy, experiential, or luxurious, love always finds the most fitting expression. May you all find the perfect atmosphere for your love story.
The ice hockey schedule for the Milano Cortina 2026 Winter Olympics, featuring preliminary rounds, quarterfinals, and medal matches for both men's and women's tournaments from February 5–22. All game times are listed in Eastern Standard Time (EST).

light phenomenon
propagation of light
laser alignment
shadow formation
The formation of a solar or lunar eclipse
pinhole imaging
inverted real image
reflection of light
definition
When light hits the surface of an object, it is reflected back by the surface of the object. This phenomenon is called reflection of light.
law of reflection
Reflected ray, incident ray and normal are in the same plane
Reflected rays and incident rays are located on both sides of the normal
The angle of emission is equal to the angle of incidence
Reversibility of light path
three lines coplanar Separation of two lines Two angles are equal
two reflections
reflection of mirror
Reflective surface is smooth
The incident light is parallel and the reflected light is also parallel
appear lighter or darker
follow the law of reflection
Example
Special: Corner reflector
blackboard reflective
diffuse reflection
Reflective surface is rough
The incident light is parallel and the reflected light is in all directions
Visible from all angles, soft and not shiny
follow the law of reflection
Example
movie curtain
blackboard
invisible light
infrared
UV rays
dispersion of light
White light can be broken down into red, orange, yellow, green, blue, indigo and violet
The three primary colors of light: red, green, and blue
refraction of light
definition
When light passes obliquely from one substance into another, the propagation direction is usually deflected. This phenomenon is called refraction of light
Laws of refraction
The refracted ray, incident ray and normal are in the same plane
The refracted ray and the incident ray are located on both sides of the normal
The angle of refraction increases as the angle of incidence increases and decreases as the angle of incidence decreases.
When light enters other transparent substances obliquely from the air, the refraction angle is smaller than the incident angle
In the refraction of light, the light path is reversible
application
The bottom of the pool becomes shallow
Pen is misplaced
plane mirror imaging
principle
law of reflection of light
Imaging features
The image is equal to the size of the object
The virtual image formed by a plane mirror can only be observed with the eyes and cannot be presented with a light screen.
The distance from the image to the plane mirror is equal to the distance from the object to the plane mirror
The line connecting the image to the object is perpendicular to the mirror surface
