Redshift and Doppler Shift 3D Explorer Passo a Passo
O Redshift and Doppler Shift 3D Explorer comeca assim que a pagina carrega: arraste para orbitar, role para ampliar e teste as predefinicoes de movimento. Tudo roda no seu proprio dispositivo - sem instalacao, sem conta.
Passo 1 - em repouso
Pressione Em repouso e note que o marcador escuro fica na linha de repouso do hidrogenio-alfa em 656.28 nm, com z = 0.
Passo 2 - aproximando e afastando
Pressione Aproximando (blueshift) e veja o marcador se mover para o violeta com z = -0.0500; depois pressione Afastando (redshift) e veja o marcador se mover para o vermelho com z = 0.0500.
Passo 3 - lei de Hubble
Pressione Lei de Hubble e leia no painel a velocidade de recessao e o redshift de exemplo para uma galaxia a 100 Mpc, alem da faixa de tensao do 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.
