Summary
Visibility challenges exist for cricket balls in day-night matches. Red, white, and pink cricket balls can have low contrast against various backgrounds, impacting player and spectator experience.
Area of Science:
- Sports Science
- Optics
- Human Factors
Background:
- Day-night cricket matches present unique visibility challenges.
- The colour and condition of cricket balls change over time.
- Environmental factors like lighting and background significantly influence ball visibility.
Purpose of the Study:
- To investigate the visibility of new and old red, white, and pink cricket balls.
- To assess ball visibility under lighting and background conditions typical of day-night cricket matches.
Main Methods:
- Modeled luminance contrast signals for a typical observer.
- Measured spectral reflectance of new and old balls (red, white, pink).
- Collected spectral data from backgrounds and illuminance at Lord's Cricket Ground during day-night conditions.
Main Results:
- Old red and pink balls showed minimal contrast against grass, pitch, and crowd.
- New pink balls had low contrast against the crowd at dusk.
- Pink and white balls (any age) exhibited low contrast against the sky at dusk.
Conclusions:
- Visibility issues with pink balls are supported by data.
- Red and white balls also face visibility challenges in certain conditions.
- Variable ground conditions and ball ageing complicate maintaining ball visibility in day-night cricket.

01:16Focusing of Light in the Eye
2.8K
Light rays enter the eye through the cornea, a transparent dome-shaped tissue that is the eye's outermost layer. The cornea bends or refracts, light rays traveling to the pupil. The shape of the cornea determines how much of the light is bent and whether the image will be focused correctly on the retina at the back of the eye. Once the light has passed through both refraction layers, it converges into a single focal point onto a small area. This is where photoreceptors start transforming...

02:16Light Acquisition
8.5K
In order to produce glucose, plants need to capture sufficient light energy. Many modern plants have evolved leaves specialized for light acquisition. Leaves can be only millimeters in width or tens of meters wide, depending on the environment. Due to competition for sunlight, evolution has driven the evolution of increasingly larger leaves and taller plants, to avoid shading by their neighbors with contaminant elaboration of root architecture and mechanisms to transport water and nutrients.

01:20Projectile Motion
15.3K
An object thrown in the air follows a parabolic path under the influence of Earth's gravitational force. The motion of such an object is called projectile motion, and the object itself a projectile. The parabolic path followed by the projectile is called the trajectory. Some common examples of projectile motion are the launching of fireworks, a golf ball in the air, meteors entering the Earth's atmosphere, and the firing of bullets.

Sight distance on vertical curves is critical in roadway design. It ensures drivers can see far enough ahead to identify and respond to hazards effectively. This directly impacts safety, driver comfort, and the overall efficiency of the transportation network.Vertical curves are classified into crest and sag curves based on their geometry. For crest curves, sight distance is determined by the line of sight between a driver's eye and a small object on the road's surface. Design parameters for...

01:29UV–Vis Spectroscopy: Woodward–Fieser Rules
24.3K
UV–Visible absorption spectra of conjugated dienes arise from the lowest energy π → π* transitions. The light-absorbing part of the molecule is called the chromophore, and the substituents directly attached to the chromophore are called auxochromes. A strong correlation exists between the absorption maxima, λmax, and the structure of a conjugated π system. The Woodward–Fieser rules predict the value of λmax for a given...

01:05Total Internal Reflection Fluorescence Microscopy
5.7K
Total internal reflection fluorescence microscopy or TIRF is an advanced microscopic technique used to visualize fluorophores in samples close to a solid surface with a higher refractive index, such as a glass coverslip. TIRF only allows fluorophores in proximity to the solid surface to be excited. When light from a medium with a lower refractive index (such as air) hits the glass coverslip at a critical angle, the light undergoes total internal reflection stead of passing through the glass.
