Redshift and Doppler Shift 3D Explorer Langkah demi Langkah
Redshift and Doppler Shift 3D Explorer berjalan begitu halaman dimuat: seret untuk memutar, gulir untuk memperbesar, dan coba preset gerakan. Semuanya berjalan di perangkat Anda sendiri - tanpa instalasi, tanpa akun.
Langkah 1 - dalam keadaan diam
Tekan Diam dan perhatikan tanda gelap tetap pada garis diam hidrogen-alfa di 656.28 nm, dengan z = 0.
Langkah 2 - mendekat dan menjauh
Tekan Mendekat (blueshift) dan lihat tanda bergerak ke arah violet dengan z = -0.0500; lalu tekan Menjauh (redshift) dan lihat tanda bergerak ke arah merah dengan z = 0.0500.
Langkah 3 - hukum Hubble
Tekan Hukum Hubble dan baca di panel kecepatan resesi dan redshift contoh untuk sebuah galaksi pada 100 Mpc, beserta rentang tegangan H0.
Why trust these tools
- Ten-plus years of web tooling. The freetoolonline editorial team has shipped browser-based utilities since 2015. The goal has never changed: get you to a working output fast, without an install.
- No install, no sign-up. Open a tool and get a working output in seconds - nothing to download and no account to create. Tools that need heavy processing run it on our service, so even a low-powered machine gets the job done.
- Analytics stops at the page view. We measure which pages get visited, not what you type or upload inside a tool. There is nothing to sign in to and no profile is attached to your input.
- Open-source core components. The processing engines underneath (libheif, libde265, pdf-lib, terser, clean-css, ffmpeg.wasm, and others) are public and audit-able. We link to each one in its tool page's footer.
- Free, with or without ads. All tools are fully functional without sign-up. The Disable Ads button in the header is always available if you need a distraction-free run.
